The choice of locations for the survey I was helping out with was based on geology. There wasn't time/money to survey the whole wilderness area so places with different rock types were chosen. This location was chosen for its carbonate (limestone/marble sorts of rock).
The rock there seems to wear away relatively easily. There were vertical channels worn into the face of the rock, presumably warn down over the years by water runoff. There were also deep narrow crevices here and there which made walking on the snow above it interesting - wondering if there might be a crevasse beneath your feet.
Much of the rock was quite smooth, but there were also many places where little jagged peaks would form, looking much like miniature mountain ranges. These were fun to see, but could be a little painful when climbing up the slope. I'm not sure why these mountains formed when the rock around them was so smooth. One theory I have is that there are mineral imperfections and the mountains are formed when a harder rock underlies the carbonate.
