Mason Cummings, The Wilderness Society

America’s most rugged wilderness

Arrive in Idaho and prepare to be greeted by some of the most rugged and unchanged wildlands in the continental United States. From weathered mountain peaks and deep river gorges to sheer-walled desert canyons and old-growth forests, these irreplaceable landscapes offer some of the best backcountry recreation and whitewater rafting while also providing a home for wildlife emblematic to the American West.

Using cutting-edge scientific studies to map wilderness, we collaborate to study and safeguard some of the largest tracts of untouched wilderness and wildlife migration routes to protect them from off-road vehicle use and the threats of our changing climate. There are few places left unmarked by mankind, and we need your help to save them for future generations.
