Nokhu Crags is a rock formation and mountain summit in the Never Summer Mountains range of the Rocky Mountains of North America. The name is derived from the Arapaho language, Neaha-no-xhu, meaning "Eagles Nest." The 12,490-foot (3,807 m) peak is located in State Forest State Park, 2.5 miles (4.0 km) south (bearing 181°) of Cameron Pass in Jackson County, Colorado, United States. The summit lies just northwest of the Continental Divide and Rocky Mountain National Park, near the headwaters of the Michigan River. The peak is prominently visible from State Highway 14 and can be seen throughout the southern North Park basin where it is known also known as "the Crags" or "Sleeping Indian" for its resemblance to the form of a supine chief. [4] To the east lie the shallow basins of Snow Lake and the Michigan or American Lakes; to the north lies a snow filled couloir; to the west the mountain descends directly into the deep waters of Lake Agnes; and to the south lie Static Peak, Mount Richthofen, and the remainder of the Never Summer Mountain Range.

Geology

The rocks of the peak were formed as a sedimentary deposit millions of years ago in an ancient ocean basin. The entire region was subsequently thrust up with the formation of the Medicine Bow Range at the close of the Mesozoic Era. Around 24–29 million years ago, rising magma began to create volcanoes that were the predecessors of the Never Summer Mountains. The magma cooled into granitic formations and nearby, now vertical, shale metamorphosed into the hornfels that forms the present day Nokhu Crags. [5] After millions of years of erosion and glaciation, the vertical fin-like form of the Nohku Crags was exposed. Erosion continues to reshape the Crags, as evidenced by the extensive talus field at its base.

Today the mountain is a barren, almost treeless form, virtually devoid of vegetation. During the day, pika and mountain goats may be seen and heard on the steep slopes. In the afternoon light green and orange hues of lichen covering the face of the rocks becomes apparent. In the evening thousands of bats stream from nooks and crannies of the western face. In the winter the Nokhu Crags are covered with deep snow and the flanks are the scene of frequent avalanches. An avalanche in 2013 killed a skier and buried another skier for hours. [6]

Geology of the Lassen volcanic area Geology of a national park in California

The geology of the Lassen volcanic area presents a record of sedimentation and volcanic activity in the area in and around Lassen Volcanic National Park in Northern California, U.S. The park is located in the southernmost part of the Cascade Mountain Range in the Pacific Northwest region of the United States. Pacific Oceanic tectonic plates have plunged below the North American Plate in this part of North America for hundreds of millions of years. Heat from these subducting plates has fed scores of volcanoes in California, Oregon, Washington and British Columbia over at least the past 30 million years and is also responsible for activities in the Lassen volcanic area.

Lassen Peak

Lassen Peak, commonly referred to as Mount Lassen, is the southernmost active volcano in the Cascade Range of the Western United States. Located in the Shasta Cascade region of Northern California, it is part of the Cascade Volcanic Arc, which stretches from southwestern British Columbia to northern California. Lassen Peak reaches an elevation of 10,457 ft (3,187 m), standing above the northern Sacramento Valley. It supports many flora and fauna among its diverse habitats, which are subject to frequent snowfall and reach high elevations.

Chaos Crags Mountain in the Cascade range in California

Chaos Crags is the youngest group of lava domes in Lassen Volcanic National Park, California. They formed as six dacite domes 1,100-1,000 years ago, one dome collapsing during an explosive eruption about 70 years later. The eruptions at the Chaos Crags mark one of just three instances of Holocene activity within the Lassen volcanic center. The cluster of domes is located north of Lassen Peak and form part of the southernmost segment of the Cascade Range in Northern California. Each year, a lake forms at the base of the Crags, and typically dries by the end of the summer season.

Front Range Mountain range of the Southern Rocky Mountains of North America

The Front Range is a mountain range of the Southern Rocky Mountains of North America located in the central portion of the U.S. State of Colorado, and southeastern portion of the U.S. State of Wyoming. It is the first mountain range encountered as one goes westbound along the 40th parallel north across the Great Plains of North America.

Colorado Plateau

The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries.

Geology of the Death Valley area Geology of the area in California and Nevada

The exposed geology of the Death Valley area presents a diverse and complex set of at least 23 formations of sedimentary units, two major gaps in the geologic record called unconformities, and at least one distinct set of related formations geologists call a group. The oldest rocks in the area that now includes Death Valley National Park are extensively metamorphosed by intense heat and pressure and are at least 1700 million years old. These rocks were intruded by a mass of granite 1400 Ma and later uplifted and exposed to nearly 500 million years of erosion.

Never Summer Mountains Mountain range in Colorado, US

The Never Summer Mountains are a mountain range in the Rocky Mountains in north central Colorado in the United States consisting of seventeen named peaks. The range is located along the northwest border of Rocky Mountain National Park, forming the continental divide between the headwaters of the Colorado River in Rocky Mountain National Park to the local-east and the upper basin of the North Platte River to the local-west; the continental divide makes a loop in these mountains. The range is small and tall, covering only 25 sq mi (65 km2) with a north-south length of 10 mi (16 km) while rising to over 12,000 ft (3,700 m) at over ten distinct peaks. The range straddles the Jackson-Grand county line for most of its length, and stretches into Jackson and Larimer county at its northern end. A panoramic view of the range is available from sections of Trail Ridge Road in Rocky Mountain National Park. One of the northernmost peaks, Nokhu Crags, is prominently visible from the west side of Cameron Pass.

Needle Rock Natural Area

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.
