The northernmost sequoia grow in Placer County in Tahoe National Forest, and the southernmost groves live in Giant Sequoia National Monument. The first widely publicized discovery of the giant sequoia was in 1852, at Calaveras Big Trees State Park. One of these trees, named the Discovery Tree, was unfortunately felled in 1853. It was determined to be 1,244 years old. Its stump was so large it was used as a dance floor.
