The Bisti Wilderness is a 45,000-acre wilderness area located in San Juan County in the state of New Mexico. It is also known as De-Na-Zin Wilderness, and was established in 1984. The Wilderness comprises a desolate area of steeply eroded badlands, which are managed by the Bureau of Land Management. Some pockets of private Navajo land within its boundaries, however, do exist.
There was a water body here. The water disappeared, leaving behind a 1,400-foot layer of jumbled sandstone, mudstone, shale, and coal that lay undisturbed for 50 million years. 6,000 years ago the last ice age receded, exposing fossils and petrified wood, and eroding the rock into the hoodoos, which are now visible. Human civilization has existed here for more than 10,000 years. The area contains a number of Chacoan sites and a portion of the prehistoric Great North Road.
Hiking, camping, wildlife viewing, photography, and horseback riding are the activities that can be done here. Tourism brings in most of the revenue here.
