Geo 365: Dec. 5, Day 339: Joints or Faults?

Like the mudstone above the hammer, the surrounding sandstones show either joints or very small offset faults that are consistent with shear to the right in an upward direction, and to the left downward. This is an outcrop I'd like to get back to- hopefully on a warmer day. I'm not very proud of the quality of my observations from this spot, but I know part of the issue was that I wanted to get the heck out of the wind and cold.
