Me on the Mark Twain Stump
The display near the tree had the following description:
"The Mark Twain Stump in front of you has a unique story to tell. In 1891, while lumbermen were cutting other sequoia trees for grapevine stakes, lumber, and shake shingles, the Mark Twain Tree was selected for another fate - world fame.
The American Museum of Natural History in New York City wanted a cross section of a giant sequoia for display. The Mark Twain Tree was chosen to provide the slab. Through this huge tree's sacrifice, many people far from California could marvel at the immensity of sequoias. Some vowed to preserve the remaining giants as living, growing monuments."
According to a photo caption it took 13 days of chopping and sawing to bring the tree down.
