Yeah, it's really a testament to time, I think. Layers of sand building up, and then the tiny effects of erosion accumulating, bit by bit. And what I think is really cool is that while driving on House Rock Road we noticed how different the landscape was on the left and the right sides of the road - the right had red sandy dirt, the left had whitish-yellow. So while looking at these buttes it occurred to me that what must have happened is that during regimes of wind from the west, white sand accumulated, and then during eastern winds, red sand accumulated. So you could read the rocks like tree rings, and infer what the climate was like during the periods they were forming.
