These narrow rock formations are called Hogbacks. My daughter, Annie, who is an Environmental Studies and Geology major at CU Boulder told me that. It is a long narrow ridge with steep equal slopes on each side. You see these in various places throughout Colorado. This is near a very small town in Southeastern Colorado called The Wall because there are a number of these formations nearby. I find them fascinating because they are a relatively thin line of rock. Best on black. Thank you for viewing.
Yes, I have a photo of a hogback from Canyon de Chelly that our park ranger son interpreted for me. I think that there may also be some leading up to Shiprock, if not Shiprock itself.
