V2 to V3, but over half of these boulder problems are V3.
Counted from the 8 climbs here that carry a grade. Shown only where there are at least 5 of them — below that the shape is noise.

Rock, from the geologic map
Dakota Sandstone and Burro Canyon Formation (Dakota Sandstone, Burro Canyon Formation) — sedimentary; clastic; sandstone; carbonaceous sand, shale, coal beds, and chert-pebble conglomerate. Early Cretaceous, about 125 to 100 million years old.
Dakota Sandstone: yellowish-brown and gray friable to quartzitic sandstone and conglomeratic sandstone and interbedded gray to black carbonaceous shale. Contains a few thin very lenticular coal beds. Plant impressions commoon; basal conglomerate is locally present. Thickness 100-200 ft. Burro Canyon Formation: white, gray, and buff fine- to coarse-grained sandstone interbedded with green and purplish siltstone, shale, and mudstone, and thin beds of impure limestone. Sandstone is locally conglomeratic, particularly at base. Thickness a few feet to 125 feet.
This is the map unit under this crag's map point, read from the 1:100,000 sheet (Day and others, 1999, U.S. Geological Survey Open-File Report 99-0427). 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 100 m wide on the ground, so the wall itself may be the neighbouring unit. Every crag on this unit: Dakota Sandstone and Burro Canyon Formation. 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 Bureau of Land Management (federal), in Grand Junction 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.

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.

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.
