How old are giant redwood trees
AGE OF THE REDWOODS
BEFORE WE CONSIDER the age of trees, it is well to learn the secret of how they record their age. Just between the bark and the wood of a tree, there is a thin layer of cells known as a "cambium." The cambium is the growing tissue of a tree. It covers the top and sides of the wood of a tree like a thimble. Each year the cambium forms bark on the outer side and wood on the inner side. These annual rings are wider in the early life of a tree, and much smaller as the tree grows older. The size of the tree, therefore, is not always an accurate guide to its age, as the annual ring of wood may vary in width according to the difference from year to year in climatic conditions. Thick rings indicate favorable seasons and prosperous growth, and thin rings record years of excessive drought or cold and consequent stunted growth. Two Redwoods of approximately the same size were cut in the same forest; one was 1,300 years old, and the other, 2,300 years old.
Special instruments now make it possible to count the rings of small standing trees. It has not been practical, however, to make accurate counts of the rings of the larger living trees, such as the Redwoods. The age of most living Redwoods therefore cannot be definitely determined, but must be estimated by making comparisons with trees that have been cut down and their rings counted.
In order that we may more fully appreciate the age of the Redwoods, we shall compare them with some other kinds of trees.
Pinesthe story of the "Thousand-Year Pine."Many of the Sugar Pines growing in the same forest with the Sierra Redwoods have reached an age of from 300 to 500 years. I have counted the rings of two stumps, which were five feet in diameter and more than 300 years old. The Giant Yellow Pine in Yosemite Valley which was killed by beetles in 1933 is still standing and is thought to be about 400 years old.
Enos A. Mills, the well-known nature-lover who lived for many years in Estes Park, Colorado, used to tell the story of an old Yellow Pine which he called the "Thousand-Year Pine." This tree grew within sight of the cliff-dwellers' Mesa Verde, which stands near the corner of four states. The tree was cut down in 1903, and Mr. Mills made a study of its life record. He found that it had some interesting stories to tell. "Although lightning had given it a bald crown [he writes] it was still a healthy giant and waving evergreen banners more than 115 feet above the earth before it fell. The massive trunk was eight feet in diameter at breast high." In the base of the trunk, Mr. Mills found 1,047 rings of growth. In sawing off a section of the lower part of the tree trunk, the saw struck something hard, which upon examination proved to be a flint arrowhead. Another was found near by. The conclusion arrived at was that, in 1486, an Indian standing near the tree shot an arrow into it which imbedded itself in the trunk. No one knows whether the Indian was aiming at a bear that stood at bay backed up against the tree, or whether the arrowhead might be the lasting record of a battle between Indian tribes.
Mexican CypressMexico's oldest tree.The Mexican Cypress (Taxodium mucronatum) ordinarily does not attain an age of more than from 1,000 to 1,500 years. There is a tree in the State of Oaxaca, Mexico, however, called "The Big Tree of Tule," which is thought by many to be the "oldest tree in the world." It has a diameter of 40 feet at the base. Some authorities would say that the tree is at least 4,000 years old, and several have estimated its age at 5,000 years. Although the Mexican Cypress belongs to the Redwood Family, this particular tree appears to be an abnormal specimen of its kind, since no other trees of this species even approximate its size or age.
Cedarsnatives of the Eastern Hemisphere.There are no true cedars native to North America. Several kinds of trees grow in America which are called "cedars," such as the Junipers, or Red Cedars, of the eastern United States, and the Canoe Cedar and Incense Cedar of the west. There are only three species of true cedars in the world, the Cedars of Lebanon (Cedrus libani) of Palestine, the Deodar Cedars (Cedrus deodara) of the Himalaya Mountains, and the Mount Atlas Cedars (Cedrus atlantica) of northern Africa. Solomon used Cedars of Lebanon in building his temple at Jerusalem. Many of the true cedars have been planted in America, especially in California. The mile-long avenue of living Christmas trees of Altadena, California, is composed of Deodar Cedars. Some of the Cedars have been known to attain an age of 2,000 years.
Junipers.Junipers belong to the Cypress Family, a group of evergreen trees which are found throughout America. They are popularly called "Cedars." Because they often grow at high elevations, where storms are prevalent and where the soil is thin, it has long been known that they are very tenacious of life. From Waldo S. Glock, of the Carnegie Foundation (his article on "Observations on the Western Juniper" appeared in the January, 1937, issue of "Madroño: A West American Journal of Botany," we may now learn some details about their age. Of the western Juniper, he says: "The longevity of the species certainly equals that of the Coast Redwood and in a few instances rivals that of the Giant Sequoia." Studying some Junipers southeast of Lake Tahoe, in Faith and Charity valleys, he found that "those from which core samples were taken gave evidence of being between 900 and 1000 years old." One tree studied is known as the "Bennett Juniper," the largest Juniper of which there is any accurate record. It is 80 feet tall and its greatest diameter, at the ground, is 21 feet, 6 inches. The diameter five feet above the ground is about 14 feet. An exact determination of its age could not be made, but Mr. Glock says: "From the data at hand, a fair estimate in round numbers . . . is 3000 years. There can be little doubt that the tree is well over 2000 years old, since the outer foot of the trunk averages seven hundred rings."
Coast Redwoodas old as Christianity.The Coast Redwoods attain a great age. Published statements to the effect that they reach an age of 5,000 years are not justified by the facts. Authentic records do indicate, however, that at least some individuals reach the age of 2,000 years. The average age of mature trees of this species is from about 800 to 1,500 years.
Sierra Redwoodthe world's oldest trees.The Sierra Redwoods (Sequoia gigantea) as a class are no doubt the oldest living things in existence. A wedge-shaped section of a comparatively small tree which has been placed in the Mariposa Grove museum for demonstration purposes, shows by actual ring count 1,830 years of growth. The tree was about 15 feet in diameter. In order that the age of this tree may be better realized, certain pen sketches, pictures, and redwood seed and seedlings have been placed in the Museum at each side of this section. The tree lived for 268 years after the landing of the Pilgrim Fathers.
Dr. Ellsworth Huntington, of Yale University, made a study of the rings of the stumps of some big trees in Converse Basin, where they had been lumbered. In the pamphlet, The Secret of the Big Trees, he gives the following facts concerning the age of Sierra Redwood: "How old the oldest trees may be is not yet certain, but I have counted the rings of 79 that were over 2,000 years of age, and of 4 that were over 3,000 years, one of which was 3,150." Dr. Jepson states that the oldest tree whose age has been accurately determined (within minor limits of error) is 3,226 years. More recently Dr. Douglas, of the University of Arizona, made a boring in the General Sherman tree, and, although unable to make an accurate count, he considers the tree to be more than 3,500 years old. John Muir said that he found a tree stump which, when the rings were counted and estimated, showed an age of 4,000 years. It has been impossible to locate the stump which Muir mentioned, and many do not consider the record authentic.
The General Sherman and the President, of Sequoia National Park, and the Grizzly Giant, of Yosemite National Park, are usually considered the oldest trees of their kind. Of these three, it is difficult to say which is the oldest; many believe it is the Grizzly Giant.
From the foregoing, we feel safe in saying that there are thousands of Sierra Redwoods between 2,000 and 3,000 years old. Certainly, a number of them are more than 3,000 years old, and a few are possibly as much as 4,000 years old. Published statements giving ages of from 8,000 to 10,000 years are greatly exaggerated.

Giant sequoias and California redwoods (also called coast redwoods) are nature's skyscrapers. These enormous trees exist primarily in Northern California, Oregon and Washington and though they have a number of common characteristics, including distinctive cinnamon-red bark, they are different species.
Giant sequoias can grow to be about 30 feet (9 meters) in diameter and more than 250 feet (76 m) tall. The biggest of these behemoths is General Sherman, a giant sequoia in Sequoia National Park. General Sherman stands 275 feet (84 m) tall, has a 102-foot (31 m) circumference, and weighs an incredible 2.7 million lbs. (1.2 million kilograms).
Giant sequoias can live to 3,000 years, with the oldest on record living more than 3,500 years. When they die, it is often indirectly because of root rot or another weakening of the base. Fire, root rot and dry spells do not typically affect the whole tree but if they destabilize the base, gravity can eventually take the tree down, according to Scientific American. This process takes a long time, as evidenced by the fact that sequoias are some of the longest living organisms on the planet.
Mature sequoias lack branches on the lower half of their trunks. Sequoia trunks taper as they rise, forming a rounded top where individual branches sweep downward. Their green leaves are small, scale-like, and arranged in spirals. Both male and females cones are carried on the same tree.
Sequoias grow naturally along the western slope of the Sierra Nevada mountain range, between 5,000 and 7,000 feet (1,524 and 2,134 m) above sea level and far inland. That elevation provides the trees with dry mountain air necessary for their cones to open and release seeds. The snowpack from the Sierra Nevada provides sequoias with the thousands of gallons of water every day. Sequoias have shallow roots and require well-drained soil.
Because of its brittle texture, the sequoia is not a valuable lumber species. It was, nevertheless, logged extensively around the turn of the 20th century. Originally, sequoias could be found throughout the Northern Hemisphere. Today, they are found only in 77 scattered groves in Northern California. Among the places that preserve giant sequoias are Sequoia National Forest, Sequoia National Park, and Giant Sequoia National Monument.A woman stands against a giant sequoia in Sequoia National Park in California.

Droughts in California have scientists worried about sequoia health. The drought of the 2010s left many sequoias stressed from lack of water, according to Scientific American. Though sequoias usually die under their own weight, recently scientists have seen some die still standing, and others exhibiting symptoms of dehydration, including brown foliage at the top of the tree. One scientist told PBS in 2015, "The trees are definitely as stressed as we've ever seen giant sequoia."
Not all giant sequoia are suffering from the drought, however. Deborah Zierten, education and interpretation manager with the Save the Redwoods League told LiveScience that a giant sequoia's response to drought is dependent on location. "There are some parks where they have seen a decline in recent years and others where the growth seems to be the same." The differences could be attributed to fire suppression, weather, location and amount of snowmelt exposure, and density of the trees. "There could be competition in some areas," Zierten said.
Fire suppression is another threat to giant sequoias. "Giant sequoias are very dependent on fire," said Zierten. Fire helps release the seeds from their cones, recycle nutrients in the soil, reduce competition from other trees, remove undergrowth and expose bare soil in which new seedlings can take root and open holes in the forest canopy, which let in sunlight for young seedlings.
"There's been a lot of fire suppression over the last 100 or so years," said Zierten. "Some of the parks are trying to reintroduce fire to clear out that understory and stimulate growth."
Researchers are working to understand how climate change is and will continue to affect giant sequoias. Lack of precipitation from snowmelt will probably be the biggest threat, said Zierten. Increased wildfires could also impact sequoias.
These tallest of trees reach heights of more than 350 feet (107 m). The tallest tree in the world is named Hyperion, which reaches 379. 7 feet (115.7 m). Redwoods can achieve a diameter of 24 feet (7 m), and 1.6 million lbs. (725,700 kg). These giants can live to be 2,000 years old and have graced the planet for more than 240 million years. Though they once thrived throughout much of the Northern Hemisphere, today redwoods are only found on the coast from central California through southern Oregon. They do not live more than 50 miles inland, and are usually found in long belts, rather than small groves.
True to their name, coast redwoods need a moderate, coastal climate to survive. They require the area's frequent fog to protect them from dry spells and drought. Like sequoias, redwoods require abundant water to drink and have shallow root systems. Redwoods, however, get their water from rain rather than snowmelt, and therefore require consistent rainfall throughout the year. They even "create" their own rain by trapping fog in their lofty branches. With the right amount of moisture, redwoods can grow two or three feet in a year, making them one of the fastest-growing conifers in the world.
In contrast to their size, redwoods have extremely small cones — about one inch long. They have appropriately large root systems, however, often extending 100 feet (30 meters) and intertwining with the roots of other redwoods, according to the California Department of Parks and Recreation. Baby redwoods often sprout at their parents' base, latching onto their roots for nutrients. For this reason, they often grow in circular clusters sometimes called fairy rings.
The coast redwood's lumber has been highly valued historically. It is durable, resistant to rot and termites, non-warping, and relatively soft. For this reason, it has been extensively logged. Since logging began in the 1850s, 95 percent of old-growth coast redwoods have been cut down, according to the Sempervirens Fund. Today, many redwoods exist in protected forests and parks.
The changing climate presents problems for redwoods. A warmer climate may result in less rain, and perhaps more concerning, less fog, which has historically been the tree's defense against dry spells, according to an ongoing study by a group of University of California-based researchers. Fog in northern California and Oregon is on the decline because of climate change and the expanding human population along the coasts, which produce "urban heat islands," according to a UC Merced researcher with the study.
On the other hand, a long-term study conducted by the Save the Redwoods League found that coastal redwoods have seen unprecedented growth over the last 100 years. They are still trying to understand why but one theory involves lessening fog in those areas. "We can't necessarily attribute the spike in growth to any one particular thing, but we know there has been a decrease in fog in the last 100 years," said Zierten. "This means sunnier days, and on sunnier days they are able to photosynthesize a lot. That could be a possibility."
Many studies suggest that redwoods and sequoias may also play an important part in mitigating climate change, according to Zierten. The trees have the ability to pull in and store dangerous carbon, keeping it from wreaking havoc on the climate. "Ancient redwood forests store at least three times more carbon above ground than any other forests on Earth," according to a Redwoods and Climate Change Initiative study.
Zierten emphasized that these studies have focused on ancient, or old-growth, forests. The trees there are bigger so they are able to store more carbon. "Because they are such long-lived trees, they are able to keep that carbon in their wood for a very, very long time," she said. "But it's really about the forest, not the individual trees. Even the fallen logs store carbon, as do the under-story plants."
For this reason, Zierten recommends that conservation organizations focus on preserving and restoring the old-growth forests that we still have, rather than planting more and more trees. "With second-growth forests, one of our goals is to do restoration to make sure they become the old-growth forests of the future," she says. "A huge area of the range is second-growth. We need to take what we have and make sure the forests are healthy and continue to thrive. "
Restoration efforts depend on the species and location, but some common techniques include "prescribed burning, clearing out understory, thinning, cutting down smaller trees to give big trees more room to grow and invasive plant removal," said Zierten. The Save the Redwoods League also restores creeks and removes some of the many roads that were built during logging booms and cause erosion.
Furthermore, the iconic status of California redwoods may help maintain public interest in saving these climate-helping trees. Zierten encourages West-Coasters and visitors alike to explore redwoods and sequoias in places beyond Muir Woods and Sequoia National Park. "There are 93 parks that conserve redwood and sequoias," she said.
- In 1881, in Yosemite National Park, a tunnel was built through the Wawona "Tunnel" tree. It was so big that people could drive their carriages — later their cars — right through. The 2,100-year-old tree fell in 1969 under heavy snowfall (some blame the tunnel's damage). Today, there are three other privately owned tunnel trees that charge a fee to drive through. On January 8, 2017, a massive storm brought down Pioneer Cabin Tree, a popular tunnel tree that the California Department of Parks and Recreation estimated at 100 feet tall.
- A fallen coast redwood will often send up new shoots, growing new trees off of its trunk. This is called a candelabra tree.
- Redwoods and giant sequoias were used to build many of the original buildings in San Francisco, Oakland, and Sacramento in the latter 1800s.
- Redwoods and giant sequoias are adept at — though by no means immune to — surviving fire. Their bark contains no flammable pitch or resin and is extremely thick.

Sequoia in the USA - types, descriptions, sizes and photos
Sequoia (lat. Sequoia ) is a genus of trees of the Cypress family growing on the Pacific coast of North America. We all heard about redwoods more than once, both in nature studies classes at school and on TV. But what these huge trees actually look like and where they grow, few people imagine. No less surprising is the fact that there are also different types of sequoias. We first saw these amazing giants during our independent trip by car in the United States. It turns out that the sequoia tree is also a symbol of the state of California. And in this article we will introduce you to these largest trees in the world (not to be confused with baobabs!).
Types of sequoia
Sequoia is an evergreen tree belonging to the cypress family. We have already seen cypresses in California when we drove along the 17 Mile Road. Three types of sequoia trees are known all over the world, two of which grow in the USA:
- Coastal sequoia ( Sequoia sempervirens ) - grows on the coast of California in the USA;
- Giant Sequoia ( Sequoiadendron giganteum ) - common in the Sierra Nevada region;
- Metasequoia ( Metasequoia ) - grows in China.
And only giant sequoia is widely known in the world under the name sequoia . Coastal is also called redwood, or redwood ( Redwood ). It is these two species that are the largest trees in the world. The coastal sequoia is the tallest tree, and the giant sequoia is the most voluminous. The Chinese metasequoia is not surprising at all with its size.

Tree redwood is found only on the Pacific Coast in Northern California and Oregon. This species (Evergreen Sequoia, Red Sequoia) does not grow anywhere else in the world. Redwood is considered to be the tallest tree in the world on planet Earth and reaches a height of 115 meters. About 50 currently growing redwoods have a height of more than 100 meters. The thickness of the trunk reaches 6.5 meters. There are specimens of redwood sequoia aged from 1500 to 2000 years.
Hard but soft redwood bark
Giant sequoia (Sequoiadendron giganteum )
Nevada in California, at an altitude of 1500-2000 meters. This type of tree got its name because of its gigantic size. And even though their tallest trees don't exceed 95 meters, the thickness of the trunk can reach 12 meters. The oldest representative of the growing today has an age of about 3200 years. Currently, only about 30 groves of giant sequoias have survived.
An interesting fact. According to some reports, the breeding season of the giant sequoia begins when it reaches the age of about 400 years. A mandatory concomitant factor in order for the sequoia to give offspring is high temperature. Here's what we know about wildfires and their benefits to redwoods:
- Forest fires do not cause significant damage to mature trees;
- Sequoia bark, which absorbs moisture from the air like a sponge, is quite resistant to fire;
- However, the heat generated by burning the forest floor is best for opening the buds and bringing redwood seeds to the ground and germinating in soil rich in minerals after burning;
- In addition, the forest, thinned by fire, allows sunlight to break through the dense canopy of trees and creates conditions for the growth of young redwoods.
Watch Video about giant sequoia and their dependence on forest fires:
Metasecia (Metasequoia )
But there is another type of sequoia in the world - Methasecium glyptostrosa , which is growing in the proofs in China, but these trees are quite normal in size. This species of sequoia is on the verge of extinction and is listed in the Red Book. They are very rare, and only on the slopes of mountains in remote areas of the Chinese provinces. That is, the ordinary tourist is not available. But the American sequoias - redwood and giant can be seen both from the car window, and take a walk along the forest paths in a grove among majestic trees.
Sequoia in the USA
When we traveled around the USA by car during our World Tour - One World, we spent a lot of time getting to know the largest trees in the world. So, let's figure out where to go if you have a desire to get acquainted with coastal and giant sequoias in the USA.
An interesting fact
The thickness of the trunk of a giant sequoia reaches 12 meters in diameter. This is enough to fit a whole house inside it or to draw a highway!
Redwood Coastal Sequoias
The natural conditions in Northern California National Parks where the Sequoia grows are ideal for these giant trees. Redwood can be seen in the following US parks and conservation areas:
- Redwood National Park ( Redwood national and state parks ) includes several state parks, which can be accessed for a fee. If you are on the highway and just going north, then you do not need to pay for it. And if you leave the highway to take a walk, then an annual subscription to national parks (Annual pass) is valid throughout the territory, except for state parks - Del Norte Coastal Redwood State Park and Jedediah Smith Redwoods State Park - where you have to pay separately.
- Muir wood National Monument near San Francisco. There is an annual pass to the national parks.
- If you are traveling in California by car from San Francisco to the north, you can also drop by Humboldt Redwoods state park and Avenue of the giants , fee separate. There you can drive your car through a tree for $5 ( Shrine Drive-thru tree ).
Sequoias are the tallest trees in the world
Highway 101 is even called Redwood Highway after its main attraction. You can just drive along the highway and admire the sequoias growing on its sides. And here redwood grows without the protection of national parks. And knowledgeable people will go not only along the 101 road, but also along the 199 highway in Oregon, which also bears the proud name redwood highway . And as it seemed to me personally, here the trees are more beautiful, and the track is prettier. And it’s even more pleasant that you are driving, and the sequoias themselves are growing around, which even becomes inconvenient that people cut a road in the rock and disturbed the tranquility of nature. So, Redwood Highway is:
- Route 101 in Northern California from the Golden Gate Bridge in San Francisco to Crescent City;
- parallel to Avenue of the Giants in the Humboldt State Park area;
- Route 199 in Oregon.
Map of the Humbolt Park (Avenue Giants)
Giant Sequoia General Giant California of the USA in the Sierra Nevada Mountains, and to admire these trees, you can visit three national parks:
- giant forests ( Giant Forst listen)) in Sequoia National Park ( Sequoia national park ). The entire park consists of giant sequoia trees, and the famous tree General Sherman , to which a whole queue is lining up. It is the largest and heaviest tree in the world. Its height is 84 meters, the circumference of the trunk at the ground exceeds 31 meters, the volume is about 1500 m 3 , and the mass is estimated at 1900 tons!
- General Grant Grove ( Grant grove ) in Kings Canyon National Park ( Kings canyon national park ) - this small area is located next to Sequoia Park and is easily accessible, unlike the rest of Kings Canyon.
- Mariposa Grove ( Mariposa grove ) in Yosemite National Park ( Yosemite national park ). Here the giant sequoias are presented in all their splendor!
Where Sequoia Grows
Sequoia trees grow on the US West Coast. And when we traveled by car through the national parks of America, we visited several parks in the state of California, where we saw coastal and giant sequoias in all their glory:
- Redwood National Park , about which they wrote a detailed article. This is the place where coastal redwoods grow in their most natural environment;
- The Redwood Highway has been a pleasure to ride in both California and Oregon;
- As for the giant sequoia, we have visited all three places where they grow: Sequoia Park, Grant Grove in Kings Canyon and Mariposa Grove in Yosemite;
- But we didn't get to Humboldt Park , because in the evening we were in a hurry to come to Eureka and rushed along the highway with a breeze and did not stop at the Avenue of the Giants. Nevertheless, the evening drive turned out to be very inspiring, and we took many photos from the car window. You can see them in a post about the Golden Gate Bridge in San Francisco, Cape Point Reyes and the Northern California road.
Sequoias with a tunnel in the trunk for cars and pedestrians
In January 2017, it became known that the most famous sequoia with a tunnel in the trunk , the Pioneer Cabin Tree, fell in California. This giant sequoia in the US became famous for having a tunnel in the trunk that a car could drive through. A tree that was growing in Calaveras Big Trees State Park was downed by a violent storm, making worldwide news and sparking an unprecedented interest in sequoias.
The original tunnel at the base of this giant sequoia was made in the late 1980s at the request of the owner of the Murphys Hotel. It was a tourist attraction, because it was incredibly interesting for people of that time to pass and even drive through the trunk, and then tell all their friends about it. So more and more people learned about this interesting place and they increasingly came to the park and stayed at the hotel.
This particular tree was chosen for cutting the tunnel due to the fact that it already had a huge scar from a forest fire. In fairness, it must be said that the idea of the tunnel was not new and, according to the idea of the hotel owner, this sequoia tree was supposed to compete with the already well-known Wawona Tree in Yosemite's Wawona Tree in the United States, which was tunneled much earlier, in 1881, in order to attract as many visitors to the park as possible. And although the Wawona sequoia in the Mariposa Grove stood much less (only until February 1969), some older Americans still remember the car tunnel in it.
Interesting fact: Fallen sequoia with a tunnel on January 8, 2017 was not the only one in California. At the turn of the 19th and 20th centuries, it was very fashionable in the western United States to make such tunnels in giant trees in order to attract everyone's attention and develop automobile tourism. After all, through it it was possible not only to walk or ride a bicycle, but also to drive inside the sequoia by car. However, this trend caused irreparable damage to nature and was quickly stopped.
More than a century has passed since then, and almost all the trees with car tunnels have collapsed. The Pioneer Cabin Tree was the last such tree of its kind, and now it has also fallen. However, you can still see a couple of giant sequoias with a tunnel for pedestrians on the West Coast of the United States and three coastal sequoias with car tunnels.
California Tunnel Tree
Giant sequoia tunnels:
- California Tunnel Tree in Mariposa Grove (Yosemite National Park). The tunnel was made in 1895 in such a way that a horse-drawn carriage could pass through this giant sequoia. Today, the tunnel can only be walked or cycled through.
- Dead Tunnel Tree in Tulumne Grove, also in Yosemite National Park. It was the very first growing giant sequoia to be tunneled through (earlier tunnels were already made in fallen tree trunks).
Coastal Redwood Vehicle Tunnels:
- Chandelier Tree is the most famous tunnel tree in the United States and is located in Drive-Thru Tree Park in Leggett, California USA ). Its height is 96 meters. The tunnel was made in the late 30s of the XX century, its width is 1.8 m and the height is 2.06 m. Anyone can drive through the sequoia in a car and take a photo of their car inside the tree for 5 US dollars. See website for details and directions.
- Two other tunneled coast sequoias grow along US 101 in northern California at Klamath (Klamath) and Myers Flat (Myers Flat).

How many years do sequoias live?
Sequoias are the tallest trees in the world. They grow up to about 500 years, and then begin to dry out. The real giants among the redwoods are mammoth trees that live on the Pacific coast of North America in the mountains of California. They reach a height of more than 100 meters, and live up to 2.5-3 thousand years!
Sequoia National Park, based in this area, is a popular tourist attraction. Every year, thousands of people come to California to see the forest giants growing here with their own eyes.
These giant trees are named after the Indian chief Sequoia, the inventor of the Cherokee alphabet

How long do trees live?
How long do trees live? How long a tree lives, it is interesting for many to know. The Internet is literally full of such questions. And most often they are interested in how long fruit trees live. Even children know how to determine the age of a tree: you just need to count
Where do gazelles live?
Where do gazelles live? This animal even has a name as beautiful and graceful as the gazelle itself. Knowing this, people, wanting to please someone, compare it with a gazelle and say: “slender as a gazelle” or “fast as a gazelle”. Gazelle is indeed both slender and fast.
