In which country are the rock formations called “hoodoos” shown in the picture located?

The Bisti/De-Na-Zin Wilderness is a 45,000-acre (18,000 ha) wilderness area located in San Juan County in the U.S. state of New Mexico. It is a desolate area of steeply eroded badlands.

The Bisti/De-Na-Zin Wilderness is a rolling landscape of badlands which offers some of the most unusual scenery found in the Four Corners Region. Time and natural elements have etched a fantasy world of strange rock formations made of interbedded sandstone, shale, mudstone, coal, and silt. The weathering of the sandstone forms hoodoos - weathered rock in the form of pinnacles, spires, cap rocks, and other unusual forms. Fossils occur in this sedimentary landform. Translated from the Navajo language, Bisti (Bis-tie) means "a large area of shale hills." De-Na-Zin (Deh-nah-zin) takes its name from the Navajo words for "cranes."

Millions of years ago, these badlands were a coastal swamp in an inland sea, alive with large trees, reptiles, primitive mammals, and meat-chomping dinosaurs.

The Navajo (Diné)—whose lands intersect and border these protected acres—gave the area its dual names: Bisti, meaning a “large area of shale hills,” and De-Na-Zin, from the word for “standing cranes.”

Humans have occupied the area almost continuously since 10,000 BC. The area contains numerous Chacoan sites and part of the prehistoric Great North Road, used to connect major Chacoan Anasazi sites in the San Juan Basin.
