One of the largest—and last—remaining wild places in North America, the Crown of the Continent ecosystem is a ten-million acre expanse of land whose untouched wilderness harkens back to the days of Lewis & Clark. View photos taken by conservationist Gene Sentz, co-founder of the Friends of the Rocky Mountain Front, who has spent three decades working to protect the Rocky Mountain Front. Earthjustice has worked with organizations like Gene's to protect the Front, the surrounding landscape and the wildlife that reside there from harmful development.
