Ansel Adams, the late American photographer and conservationist, was born 110 years ago Monday. His sweeping images of U.S. landscapes helped galvanize the country's nascent conservation movement last century, part of a decades-long effort to expand the national park system and popularize the idea of preserving wilderness.

Snake River, Grand Teton National Park, Wyoming


Canyon de Chelly National Monument, Arizona


Jackson Lake, Grand Teton National Park, Wyoming


Leaves in Glacier National Park, Montana


Rocky Mountain National Park, Colorado


Crystal Spring, Carlsbad Caverns National Park, New Mexico


Castle Geyser Coye, Yellowstone National Park, Wyoming


McDonald Lake, Glacier National Park, Montana


Saguaro National Monument, Arizona
