When “Mark Twain” was cut down in 1891, the giant Sequoia was 1,341 years old and measured 331 ft (100.9 m) high and 90 ft (27.4 m) in circumference at the base. Today a stump is all that remains of the once thriving tree that might have survived another thousand years. A cross section is on display at the American Museum of Natural History in New York; the curator at the time marked on its annual rings selected events of human history.
