Flowing south from Silverton to Durango, the Animas River drains from over one million acres of the San Juan National Forest. A herd of Rocky Mountain bighorns call this area of the state home.

Bighorns can be found in hard to reach steep, vertical cliff areas. The elevation rise from Lime Creek to the summit of North Twilight Peak is 4,075' in only one and a half miles. It is important to use quality optics. Be aware of bears while camping.
