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.
14,000 foot Mt. Eolus, Missionary Ridge, Putnam Basin, steep cliffs, canyons and drainages along the Animas River, broad mesas, buttes and rolling foothills all create a dynamic landscape.
Alpine areas support moss, wildflowers, lichens, barren ground willows and grasses. Spruce, fir, aspen, ponderosa pines and open meadows can be found on the mountain sides. Aspen, oakbrush, mountain mahogany, bitterbrush found on ridges, drainages and foothills are all found within this area. Cottonwoods, willows, sagebrush and pinyon/juniper cover lower elevations.
