5.8 to 5.10, with no single grade dominating.
Counted from the 9 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 9
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 Pig Pen, Bird's Eye (2 climbs, about 60 seconds) would place up to 7 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
Landslide deposits. Cenozoic, up to about 2.6 million years old.
Deposits composed of unsorted and unstratified debris of various sizes as well as almost intact blocks of bedrock that slid and flowed down slopes are locally common in the map area. Younger landslide deposits commonly have hummocky surface morphology and are bounded upslope by crescent-shaped headwall scarps and downslope by lobate toes. Older landslide depos- its commonly lack scarps and have more muted surface morphology. Unit Qls locally includes material displaced by rotational debris slides, translational rock and debris slides, debris flows, and possibly minor earth flows (as defined by Cruden and Varnes, 1996). Some landslides in basement rocks may have formed in rock weakened by fault- ing and deep-seated gravitational spreading. The sizes and lithologies of the clasts and the particle sizes of the matrices of these deposits reflect those of the displaced surficial deposits and bedrock units. Some of the largest landslides and landslide deposits form on unstable slopes that are underlain by shale of the Belden Formation (*b) and sedi- ments of Dry Union Formation (Nd). The large landslide deposit just south of Pine Creek formed largely by the remobilization of surficial deposits, but it probably also includes the underlying sediments of the Dry Union Formation (Nd). The relatively fresh landslide scarps in this deposit suggests that some of the movement occurred during the Holocene. Some landslide deposits with relatively smooth topography may be as old as early Pleistocene. Estimated thickness possibly as much as 60 m
This is the map unit under this crag's map point, read from the 1:100,000 sheet (Kellogg and others, 2017, U.S. Geological Survey Scientific Investigations Map 3382). 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: Landslide deposits. 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 Royal Gorge Field Office. It lies inside wild and scenic river.
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.
