Mexican Hat is a town about 20 miles north of Monument Valley and named for a local rock formation. We passed it on the way to Monticello, Utah which is where we are parked now.
While we were still a distance away from Mexican Hat, we noticed the mountains in the background were strikingly colored and and even more strikingly patterned.
We took the side road to the rock formation, and the reason for the patterning became more apparent.
I don’t know what causes the different colors in the layers of rock but the layers look like they were lifted in the middle into a graceful curve, and then later eroded along the lines of the layers. I think this type of formation is called a geosyncline.
This pattern though, was repeated in much smaller form near Mexican Hat rock. This is a small hill only about 150 feet high, whereas the mountains in the background were at least a couple of thousand feet high. This patterning looks a bit like a Serape and may be part of the reason why it is called Mexican Hat.
