Description
White sandstone under red crust: this area of the Gold Butte sometimes called Devil's Fire, shows a unique weathering pattern on the sandstone. From the Nevada tourism website: 10-16 million years ago, the Earth�s crust in this region was stretched and thinned. Faults were created that uplifted and exposed the Aztec Sandstone and cracked the rock into blocks. The cracks�called joints�allowed dissolved minerals in the groundwater to flow through the rock, which later crystallized in the arid climate. During erosion, these mineralized joints are more resistant and form the thin fins that are now visible.
