Rock, from the geologic map
Dakota Sandstone and Purgatoire Fm (Dakota Sandstone, Purgatoire Formation) — sandstone, shale. Albian, about 113 to 100 million years old.
Sandstone and shale
This is the map unit under this crag's map point, read from the 1:500,000 sheet (Horton and others, 2017, U.S. Geological Survey Data Series 1052). The point can be a few hundred metres from the rock, a cliff often stands on the line between two units, and at that scale a line on the map is about 500 m wide on the ground, so the wall itself may be the neighbouring unit. Every crag on this unit: Dakota Sandstone and Purgatoire Fm. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Access & safety
We don't know who manages this ground: PAD-US doesn't map this point as protected land, which most often means it is private. Find out whose it is before you go.
Nobody has yet read the land manager's own rules for this crag and written them down here, so treat the above as where you are, not as what you may do.
