Bisti Wilderness Area, New Mexico
mages of our hike through the BLM-managed wilderness area known as "Bisti Badlands", on Friday, January 28, 2011. Bisti [pronounced "BIS-tie"] is Navajo for "badlands". Located about 35 miles south of Farmington, NM, this seldom-visited area is a wonderland of fantastical hoodoos, mushrooms, balanced rocks and petrified wood. The siltstones and mudstones formed during the Cretaceous Period from swamps rich in organic material, and now form the white-gray and tan slopes and hills known as the Fruitland formation. Capped with much harder sandstones and seams of coal, these amazing sculptural forms are an example of "differential erosion", whereby the softer underling rock erodes much more quickly than the overlying rock. Eventually, the caps fall off, and the exposed tier of mudstone quickly erodes away. Despite its other-worldy and rather desolate appearance, this land is very fragile; a careless step could quickly destroy what it took Mother Nature millions of years to create.
