Tahoe-Yosemite Trail Tahoe-Yosemite Trail The Tahoe-Yosemite Trail (TYT) is a long-distance trail in the Sierra Nevada mountain range of California. The trail courses from Meeks Bay at Lake Tahoe to Tuolumne Meadows in Yosemite National Park. The trail is a foot and equestrian path that passes through the Desolation, Mokelumne, Carson-Iceberg, Emigrant, and Yosemite Wilderness Areas and the Meiss Country (Dardanelles) Roadless Area.

Yosemite National Park alpine glaciers, bucking established scientists such as Josiah Whitney, who regarded Muir as an amateur. Muir wrote scientific papers on the area's biology. Landscape architect Frederick Law Olmsted emphasized the importance of conservation of Yosemite Valley. Overgrazing of meadows (especially by sheep), logging of giant sequoia, and other damage caused Muir to become an advocate for further protection. Muir convinced prominent guests of the importance of putting the area under federal protection; one such guest was Robert Underwood Johnson, editor of "Century Magazine". Muir and Johnson lobbied Congress for the Act that created Yosemite National Park on October 1, 1890.
