What's here
5.8 to 5.13, with no single grade dominating.
Counted from the 17 climbs here that carry a grade. Shown only where there are at least 5 of them — below that the shape is noise.
How well located
Position on wall known 18
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 Good Trouble, Jesus Liquid, Drug Test (3 climbs, about 90 seconds) would place up to 15 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
Ash-flow tuff of main volcanic sequence — volcanic. Cenozoic, about 34 to 23 million years old.
Includes many named units
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: Ash-flow tuff of main volcanic sequence. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Photographs near this crag

Straight line between the two crags' map points, each of which can be some way from its rock. For when this wall is full, or the sun has found it.

Access & safety
The map point for this crag is on land managed by Bureau of Land Management (federal), in San Luis Valley Field Office.
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.
Rules for all Bureau of Land Management land
- Fees
- Developed campgrounds are fee sites: at Shelf Road, Sand Gulch is $20 a night for an individual site and $40 for a group site, with no drinking water, hook-ups or trash service. Where a fee area is posted, you must register and pay within 30 minutes of entering it.
- Overnight
- Camping more than 14 days in any 30-day period at any one location is prohibited, including in a campground, and afterwards you must move at least 30 air miles. Personal property may not be left unattended anywhere on public land for more than 48 hours.
Read on Bureau of Land Management's own pages, checked 2026-09-29 by John Crawford. What they require, in full, or their own climbing page. These apply to the manager's whole holding; anything specific to this crag is above.
Nearby, from OpenStreetMap
- Toilets
- 876 m away (map)
- Mapped parking
- 784 m away (map)
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.
