Position on wall known 4
No route here has its own point yet. The map pin is the crag. At the wall? Survey it: 30 seconds per route.
The order of the climbs along this wall is known from the open catalogue, so a few surveys go a long way: standing at Left Side, Chimney (2 climbs, about 60 seconds) would place up to 2 more climbs between them. Survey the wall →
“Up to” because the estimate between two surveyed routes is only used when they turn out to be close enough together on the ground.
Rock, from the geologic map
Morrison, Ralston Creek, and Entrada (or Exeter) Fms (Morrison Formation, Ralston Creek Formation, Entrada Sandstone) — sandstone, mudstone, claystone. Jurassic, about 164 to 145 million years old.
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: Morrison, Ralston Creek, and Entrada (or Exeter) Fms. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Access & safety
The map point for this crag is on land managed by Comanche National Grassland (federal). It lies inside national grassland.
The boundary is close. Land managed by Piñon Canyon Maneuver Site comes within 250 m of this point, and the point is not the rock — the wall itself may be on the other side of the line. Check which before you rely on either one's rules.
Land manager from USGS PAD-US (public domain), read 2026-09-29. It is the manager of the crag's map point, which can be a long way from the wall. What you may do on the rock is the manager's to say, not ours.
Nobody has yet read Comanche National Grassland'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.

Distances are a straight line from this crag's map point, which can itself be hundreds of metres off; a road may be much longer. Mapped by OpenStreetMap contributors (ODbL), so a toilet missing here may simply be unmapped. Parking here is what OSM has drawn nearby, not a guidebook's directions.
