Visitors to Yosemite National Park climb Olmsted Point

Boulders, Yosemite National Park

This Month in Photo of the Day: National Geographic Magazine Features

Boulders perch randomly at Olmsted Point in Yosemite National Park. A glacier sculpted the 92-million-year-old bedrock here and left the boulders, plucked from a nearby mountain, when it retreated. The rocks, along with grooves in the bedrock, show the path of the glacier.
