Though not of particularly high elevation for the region, Hesperus Mountain is visually quite prominent, as it is near the southern edge of the San Juan Mountains and rises over 7,000 ft (2,100 m) above the area.
Hesperus is notable as the Navajo People's Sacred Mountain of the North, Dibé Ntsaa, which marks the northern boundary of the Dinetah, their traditional homeland. It is associated with the color black, and is said to be impregnated with jet. When First Man created the mountain as a replica of mountains in the Fourth World, he fastened it to the ground with a rainbow and covered it in darkness.[5]
Along with Ute the La Plata Mountain Range has also been the early homeland of the Navajo People who had settled on and near this mountain and the La Plata Mountain Range.
