The 38,305-acre Bisti/De-Na-Zin Wilderness is a remote desolate area of steeply eroded badlands which offers some of the most unusual scenery found in the Four Corners region of the United States. Time and natural elements have etched a fantasy world of strange rock formations and fossils. It is an ever-changing environment that offers the visitor a remote wilderness experience. Translated from the Navajo language, Bisti means “a large area of shale hills” and is commonly pronounced (Bis-tie). De-Na-Zin (Deh-nah-zin) takes its name from the Navajo words for “cranes.” Petroglyphs of cranes have been found south of the wilderness area.
The two major geological formations found in the wilderness are the Fruitland Formation and the Kirtland Shale. The Fruitland Formation makes up most of what the visitor will see while in the badlands and contains interbedded sandstone, shale, mudstone, coal, and silt. The weathering of the sandstone forms the many spires and hoodoos (sculpted rock) found throughout the area. The Kirtland Shale contains rock of various colors and dominates the eastern part of the wilderness.

You wont find much in the way of green here

But you will find some incredible geology

Geology which makes those without a background in it, standing there scratching our heads in wonder

Just when you begin to think that maybe you understand one thing, you go over a hill, or around a bend and. . .

. . . wonder; just what planet you're on?
Those last two are amazing!!!!
