In Crimea and the Caucasus, thousands of years ago, there were groves of giant trees—sequoias. However, the great ice age wiped out these giants, leaving only a few remnants in the mountains of California.
When one of the California sequoias was cut down, researchers counted 3,500 annual rings on its stump. This tree lived for 35 centuries and reached a height of 150 meters (approximately 492 feet).
In the hollow of another sequoia, a lecture hall was created. It housed a piano, a lectern for the speaker, and 32 chairs for the audience. When 50 tourists enter the hollow, it’s safe to say they don’t feel cramped. Meanwhile, in the trunk of another sequoia that was toppled by a storm, a garage for large tractors was set up.
