A couple weeks ago, we took our first field trip to the Medicine Bow National Forest to begin a study of geology. That trip was mainly to test our kit, pack out, and do some navigation training, which was successful. On the way out of the forest, we saw a formation at UTM grid coordinates 13T DF 7305 5830, that looked different. There was a peculiar pattern on one of the exposed faces of a rock:
It turns out that is some sort of igneous rock, which I'll get to later. Here's a closer look at that pattern on the shear face:
The angle of the sun was quite good, to show the relief of that pattern. My best guess is that is a flow pattern created when that rock was formed.
