Yosemite is one of natures greatest classrooms and what better way to learn about the forces that shaped Yosemite and the Sierra Nevada than going on a Ranger led walk.
Thursdays at 2:00 (February only; weather permitting) learn about the Geology of Yosemite Valley. The walk starts at the front of the Visitors Center in Yosemite Village and lasts for an hour and a half (bring good shoes).
