Roaring Fork River is a tributary of the Colorado River, approximately 70 miles (110 km) long, in west central Colorado in the United States. The river drains a populated and economically vital area of the Colorado Western Slope called the Roaring Fork Valley or Roaring Fork Watershed, which includes the resort city of Aspen and the resorts of Aspen/Snowmass.
The Crystal River is a tributary of the Roaring Fork River, approximately 40 mi (64 km) long, in western Colorado in the United States. It drains a glacial valley, called the Coal Basin, south of Carbondale which was historically known as a center of coal mining in southwestern Colorado. It rises in northern Gunnison County in the Elk Mountains on the north side of Schofield Pass, passing through the ghost town of Crystal City, still inhabited by a few summer residents. It then flows north past Marble, then into Pitkin County past Redstone. It joins the Roaring Fork below Carbondale. State Highway 133 follows the river along much of its route north of Marble.
White River is a river, approximately 195 miles (314 km) long, in the U.S. states of Colorado and Utah and is a tributary of the Green River.
The North Fork Gunnison River is a tributary of the Gunnison River, 33.5 miles (53.9 km) long, in southwestern Colorado in the United States. It drains part of the southwestern flank of the Elk Mountains northeast of Delta.
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.
Capitol Peak is a high and prominent mountain summit in the Elk Mountains range of the Rocky Mountains of North America. The 14,137-foot (4,309 m) fourteener is located in the Maroon Bells-Snowmass Wilderness of White River National Forest, 8.7 miles (14.0 km) east by south of the community of Redstone in Pitkin County, Colorado, United States.
Mount Sopris is a twin-summit mountain in the northwestern Elk Mountains range of the Rocky Mountains of North America. The 12,965-foot (3,952 m) mountain is located in the Maroon Bells-Snowmass Wilderness of White River National Forest, 6.6 miles (10.7 km) north by northeast of the community of Redstone in Pitkin County, Colorado, United States.
Mount Lamborn is a mountain summit in the West Elk Mountains range of the Rocky Mountains of North America. The 11,402-foot (3,475 m) peak is located in Gunnison National Forest, 5.9 miles (9.5 km) southeast by south of the Town of Paonia in Delta County, Colorado, United States. The summit of Mount Lamborn is the highest point in Delta County. Together with nearby Landsend Peak to the southwest, it lies at the western edge of the West Elks, rising dramatically nearly 6,000 ft above the valley of the North Fork Gunnison River to the west.
The South Fork Republican River is a river that arises in Lincoln County, Colorado, United States, and flows east-northeastward for about 171 miles (275 km) through Kit Carson and Yuma Counties, Colorado, and Cheyenne County, Kansas, to a confluence with the Republican River in Dundy County, Nebraska. Bonny Reservoir is located on the South Fork Republican River in Yuma County, Colorado.
Crow Creek is a 153-mile-long (246 km) waterway of southeastern Wyoming and northern Colorado. Crow Creek is formed by the merger of the South Fork of Crow Creek with the Middle fork of Crow Creek, with the quick addition of the North Fork of Crow Creek about 1.5 miles (2.4 km) downstream. All the major tributaries of Crow Creek begin in the Laramie Range and flow eastward. The headwaters of the North Fork are dammed to form North Crow reservoir, which supplies the city of Cheyenne. The middle fork is also dammed forming Granite and Crystal reservoirs, also supplying water for Cheyenne. The South Fork is the only unobstructed section and flows most of the year but not all the way to Cheyenne. Other tributaries of Crow Creek below the reservoirs are Sand Creek, Spring Creek and Brush Creek, none of which flow year round. Crow Creek continues in an eastward direction passing through the city of Cheyenne, and then heads east and south into Colorado where it eventually meets the South Platte River.
Elk River is a 34.2-mile-long (55.0 km) stream in Colorado. It flows from a confluence of the North Fork Elk River and Middle Fork Elk River in Routt National Forest north of Steamboat Springs to a confluence with the Yampa River.
Middle Fork Elk River is a 3.5-mile-long (5.6 km) stream in Colorado. It flows from a confluence of Gilpin Creek and Gold Creek in Routt National Forest north of Steamboat Springs to a confluence with the North Fork Elk River that forms the Elk River.
The North Fork White River is a 33.0-mile-long (53.1 km) tributary of the White River. The river's source is Wall Lake in the Flat Tops Wilderness Area of Garfield County, Colorado. It joins with the South Fork White River in Rio Blanco County to form the White River.
The South Fork White River is a 38.6-mile-long (62.1 km) tributary of the White River. The river's source is in the Flat Tops Wilderness Area of Garfield County, Colorado. It joins with the North Fork White River in Rio Blanco County to form the White River.
South Fork Eagle River is a 6.9-mile-long (11.1 km) tributary of the Eagle River in Eagle County, Colorado. The river flows from a source east of Tennessee Pass in the White River National Forest to a confluence with the East Fork Eagle River that forms the Eagle River.
North Fork Elk River, or North Fork Elk Creek is a 15.2-mile-long (24.5 km) tributary of the Elk River in Routt County, Colorado. It flows from a source on the northeast slopes of Big Agnes Mountain in the Mount Zirkel Wilderness to a confluence with the Middle Fork Elk River that forms the Elk River.
South Fork San Miguel River is a 6.5-mile-long (10.5 km) tributary of the San Miguel River in San Miguel County, Colorado. The river flows north from a confluence of the Lake Fork and the Howard Fork to a confluence with the San Miguel River west of Telluride.
Elk Knob is a mountain in the North Carolina High Country, north of the community of Meat Camp. Its elevation reaches 5,538 feet (1,688 m).
Needle Rock Natural Area is located at the western edge of the West Elk Mountains of Colorado. The surrounding terrain is characterized by laccolithic mountains flanked by precipitous cliffs, extensive talus aprons, forested mesas, canyons, and spacious, well-watered intermontane basins. Needle Rock is an intrusive plug of monzonite porphyry cropping out 3.5 miles (5.6 km) east-northeast of the Town of Crawford in Delta County, Colorado, United States. At an elevation of 7,797 feet (2,377 m), the towering rock spire stands 800 feet (240 m) tall above the floor of the Smith Fork of the Gunnison River valley. The massive rock feature originated in the Oligocene geological epoch when magma intruded between existing sedimentary rocks as the crown of a buried laccolith or possibly the underlying conduit of a laccolith. Subsequent erosion has exposed the prominent rock formation seen in the natural area today.
Smith Fork is a tributary of the Gunnison River that flows in Gunnison and Delta counties in western Colorado. The river is signed as "Smith Fork Creek" where it goes under Colorado State Highway 92 in Crawford, Colorado.
