The western portion of the county descends toward the valley of the lake, but perhaps the most dominating physical feature in Salt Lake County are the Wasatch Mountains in the eastern portion of the county, famous for both summer and winter activities. The mountains are administered as part of the Wasatch-Cache National Forest. The mountains' snow is touted in state-sponsored publicity as 'Greatest Snow on Earth' for its soft, powdery texture, and led to Salt Lake City's winning the bid for the 2002 Winter Olympics. Salt Lake County has four ski resorts: Snowbird and Alta in Little Cottonwood Canyon and Solitude and Brighton in Big Cottonwood Canyon. Hiking and camping are popular summer activities. The Oquirrh Mountains border the western part of the county. These two mountain ranges, together with the much smaller Traverse Mountains at the south of the valley, delimit Salt Lake Valley, which is also flanked on the northwest by the Great Salt Lake, and on the north by the Salt Lake Anticline (including Ensign Peak).
