Sunset on Nokhu Crags. The 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 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. 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
