Needle Rock Natural Area [1] 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. [2] Needle Rock is an intrusive plug of monzonite porphyry [3] cropping out 3.5 miles (5.6 km) east-northeast (bearing 68°) of the Town of Crawford in Delta County, Colorado, United States. With an elevation of 7,797 feet (2,377 m), [4] 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 [5] as the crown of a buried laccolith [3] or possibly the underlying conduit of a laccolith. [2] Subsequent erosion has exposed the prominent rock formation seen in the natural area today.
The Needle Rock Natural Area is managed by the Bureau of Land Management. [6]
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 West Elk Mountains are a high mountain range in the west-central part of the U.S. state of Colorado.

Mendicant Ridge is a massive 12 miles (19 km) long high mountain located about 9 miles (14 km) east-southeast of Crawford, Colorado, in the Gunnison National Forest, Gunnison County, Colorado, United States.

Trending roughly northeast, Mendicant Ridge has four distinct summits that are often confused in the reference literature. From Castle Rock summit at 11,205 ft (3,415 m) on the southwest, the ridge rises to Mendicant Ridge South summit at 11,425 ft (3,482 m), then to a higher central summit at 11,603 ft (3,537 m), and finally to the Mendicant Ridge High Point located on the northeast end at an elevation of 11,841 ft (3,609 m).
