Notes: Arm has the world's widest-known branch: diameter 9.96 ft (3.04 m). Photographer H. N. Marion discovered the tree in 1936 near the now-defunct Milk Ranch Trail between Oriole Lake and Atwell Mill. Naturalist Wendell D. Flint, who first visted the tree in 1975, named it Arm because he believed the large branch resembles a giant arm.

Arm is directly in the path of the May 3, 2106 total solar eclipse.
