context_page_description: Independence Pass, originally known as Hunter Pass, is a high mountain pass in central Colorado, United States. It is at elevation 12,095 ft on the Continental Divide in the Sawatch Range of the Rocky Mountains. The pass is midway between Aspen and Twin Lakes, on the border between Pitkin and Lake counties.
  State Highway 82 traverses it, and after Cottonwood Pass to the south, is the second highest elevation of a paved Colorado state highway on a through road. It is also the second-highest pass with an improved road in the state, the fourth-highest paved road in the state and the second highest paved crossing of the Continental Divide in the U.S. Because of the heavy snowfall at its elevation, it is closed in wintertime, isolating Aspen from direct access from the east during the ski season.
  When the pass is open in warmer weather, it is a popular destination. A scenic overlook near the pass allows visitors to take in the alpine tundra environment above treeline, and offers excellent views to the east of Mount Elbert, Colorado's highest peak and the second-highest mountain in the contiguous United States.
context_section_description: At the pass, the main ridge of the Sawatch Range, and thus the Continental Divide, turns from running generally south to more southwesterly. North of the pass slopes rise to an unnamed 13,440-foot (4,100 m) peak a half-mile (1 km) away; a ridge of about the same length connects it to the nearest named summit, 13,711-foot (4,179 m) Twining Peak. To the south the ridge rises more gently around Mountain Boy Gulch to an unnamed 13,198-foot (4,023 m) summit 2 miles (3.2 km) distant. The first named summit in this direction is Grizzly Peak, Colorado's highest thirteener.
  The terrain is level enough, and the ridge broad enough, to allow for a 500-foot (150 m) parking lot along the south side of Highway 82 at the height of land. The pass is split evenly between Pitkin and Lake counties, as well as White River and San Isabel national forests. Boundaries of the Collegiate Peaks Wilderness and the Mount Massive Wilderness are near the pass on the south and north respectively. The Hunter–Fryingpan Wilderness is also nearby.
  West of the parking area is a small maintenance shed; on the east are toilet facilities. Both are maintained by the U.S. Forest Service. A paved walkway system extends to a pair of overlooks 500 feet (150 m) to the south allowing views in that direction over the Lake Creek valley to Mount Elbert, at 14,440 feet (4,400 m) the highest peak both in Colorado and the Rocky Mountains, and La Plata Peak, another fourteener and the state's fifth-highest peak. A wide dirt path continues southward three miles (4.8 km) along the ridge to an unnamed 13,020-foot (3,970 m) summit. Across the road a use path leads 2.5 miles (4.0 km) to the summits of the unnamed peak and Twining.
  The pass comes roughly in the middle of a 32-mile (51 km) stretch of Highway 82 between the two winter gates, a corridor that is sometimes referred to in its entirety as Independence Pass. Aspen is 19 miles (31 km) to the west, with Twin Lakes 18 miles (29 km) to the east. Beyond Aspen the highway continues down the valley to the mouth of the Roaring Fork at Glenwood Springs. East of Twin Lakes Highway 82 continues a short distance to its eastern terminus at U.S. Highway 24, 15 miles (24 km) south of Leadville.
  On both approaches, the dropoff is steep enough for Highway 82 to require a 6% grade and switchbacks: one on the west and three on the east. The former approach uses the narrow valley of the Roaring Fork River, a tributary of the Colorado, which rises from Independence Lake west of the pass. Its walls are steeper but shallower than those of the North Fork of Lake Creek, which drains into Twin Lakes Reservoir and the headwaters of the Arkansas River, on the east.
  The pass is above tree line, so the surrounding terrain is alpine tundra. Open grassy expanses are occasionally broken by low shrubbery and bare patches of rock, particularly on the steep slope to the north. Snow lingers in some areas year-round. Adjacent to the road and parking area are small ephemeral pools on the southwest, with a larger, permanent one north of the road.
