The Mosquito Range (elevation approximately 14,000 ft) is a high mountain range in the Rocky Mountains of central Colorado in the United States. The peaks of the range form a ridge running north–south for roughly 40 mi (64 km) from southern Summit County on the north end, then along the boundary between Lake and Park Counties. The ranges forms a high barrier separating the headwaters of the Arkansas River near Leadville from South Park and the headwaters of the South Platte River near Fairplay. The highest peak in the range is Mount Lincoln at an elevation of 14,286 ft. Other fourteeners in the range are Quandary Peak (14,272 ft), Mount Bross (14,172 ft), Mount Democrat (14,148 ft), and Mount Sherman (14,036 ft).
The mountains are faulted anticlines formed as part of the Sawatch Uplift during the Laramide orogeny around 65 million years ago (Mya). The mountains were originally contiguous with the higher Sawatch Range to the west, but were separated during the formation of the rift valley at the headwaters of the Arkansas River about 35 Mya. The range is primarily of granite. The eastern flank of the range along the rim of South Park is overlain by Paleozoic and Mesozoic sedimentary rocks. The northern end of the range was glaciated during Pleistocene time, forming U-shaped valleys in the canyons.
The high ridge of the range forms a relatively difficult barrier between South Park and the Arkansas headwaters. Several of the high peaks of the range are prominently visible from the southern side of Fremont Pass along State Highway 91 between Climax and Leadville. The range is not traversed by any major highway, but only in two places by backroads over high passes: Mosquito Pass and Weston Pass. Much of the range is located within the Pike National Forest.

Mosquito Pass, with an elevation of 13,185 ft (4,019 m), is a high mountain pass in the Mosquito Range of central Colorado in the United States. It lies on the boundary between Lake and Park counties between Leadville (west) and Fairplay (east). It also lies on the divide between the Arkansas and South Platte Rivers, which is the informal demarcation between the northern and southern parts of Colorado, east of the Continental Divide.
The Elk Mountains are a high, rugged mountain range in the Rocky Mountains of west-central Colorado in the United States. The mountains sit on the western side of the Continental Divide, largely in southern Pitkin and northern Gunnison counties, in the area southwest of Aspen, south of the Roaring Fork River valley, and east of the Crystal River. The range sits west of the Sawatch Range and northeast of the West Elk Mountains. Much of the range is located within the White River National Forest and the Gunnison National Forest, as well as the Maroon Bells-Snowmass Wilderness and Raggeds Wilderness. The Elk Mountains rise nearly 9,000 ft. above the Roaring Fork Valley to the north.
The Sawatch Uplift is a prominent geologic anticline in the Rocky Mountains in central Colorado in the United States. It was formed as a bulge in the North American Plate approximately 70–65 MYA during the Laramide orogeny that created the modern Rocky Mountains. The uplift runs north-south for about 100 miles (160 km) in central Colorado. The Sawatch Range and Mosquito Range were both formed as part of the uplift. Approximately 35 MYA, stresses in the continental plate in the center of the uplift caused the center to collapse, forming the upper Arkansas River graben. This is a trough between the Sawatch and Mosquito Range that is part of the larger Rio Grande Rift. The trough runs southward from Leadville, CO to the San Luis basin. The upper Arkansas Graben forms forms the headwater valley of the Arkansas River.
Trout Creek Pass, elevation 9,487 ft (2,892 m), is a mountain pass located in the Rocky Mountains of south-central Colorado in the United States. The pass sits atop the southern end of the Mosquito Range on the Park-Chaffee county line, between South Park and the headwaters of the Arkansas River to the west. It is traversed jointly by U.S. Highway 24 (US 24) and US 285. It is passable by most motorized vehicles and is closed only during severe winter storms. The approach from the north is mild, while the south side has a moderate 5% grade.

The Southern Rocky Mountains are a major subregion of the Rocky Mountains of North America located in the southeastern portion of the U.S. state of Wyoming, the central and western portions of Colorado, the northern portion of New Mexico, and extreme eastern portions of Utah. The Southern Rocky Mountains are also commonly known as the Southern Rockies, and since the highest peaks are located in the State of Colorado, they are sometimes known as the Colorado Rockies, although many important ranges and peaks rise in the other three states. The Southern Rockies include the highest mountain ranges of the Rocky Mountains and include all 30 of the highest major peaks of the Rockies.
The Cochetopa Hills are a ridge of uplands on the Continental Divide in Saguache County, southern Colorado, United States.
The Arkansas Hills are a mountain range in Central Colorado located between the upper Arkansas River Valley and the upper South Platte River Valley. This landmass is a continuation of the ridge known as the Mosquito Range north of Trout Creek Pass. The range continues for roughly 60 miles south-southwest from Trout Creek Pass to the town of Texas Creek. Few perennial streams flow out of the Arkansas Hills, as the area is arid. The range is in the rain shadow of the much higher Sawatch to the west across the Arkansas River Valley. The City of Salida, Colorado is the most notable municipality near the Arkansas Hills. To the south is the town of Cotopaxi, Colorado. To the east is the town of Guffey, Colorado. The highest points in the Arkansas Hills tend to be between 11,000 and 12,000 feet elevation.
