This is likely John Muir’s earliest drawing of a Giant Sequoia (albeit a dead one).
It is believed to have come from Muir’s 1869 visit to the Tuolumne Grove that is documented in My First Summer in the Sierra.
A tunnel was bored through this snag in 1878, and visitors could drive through it until 1962, when this section of Big Oak Flat Road was diverted.
