Who are these guys? That's our founder, John Muir (the guy with the beard) with President Theodore Roosevelt above California's Yosemite Valley (now part of Yosemite National Park) in 1903. Look familiar? John Muir is also depicted on the back of the California state quarter. Photo: Sierra Club Colby Library; all rights reserved.
