How well located
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 Blues Incognition, For Crying Out Loud (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
Dakota Sandstone and Burro Canyon Fm (Dakota Sandstone, Burro Canyon Formation) — sandstone, shale, conglomerate. Cretaceous, about 129 to 95 million years old.
Sandstone, shale, and conglomerate. In northwest and west-central: Lower Cretaceous. In southwest: Lower and Upper Cretaceous.
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 Burro Canyon Fm. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Reports are dated and fade on their own: wet rock after 3 days, a bad bolt after a year. No names, no text.
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.
