5.6 to 5.13, mostly around 5.10.
Counted from the 21 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 21
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 Special Bob, E.T., Depends (3 climbs, about 90 seconds) would place up to 18 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
Fan deposits. Quaternary, younger than 126,000 years.
Mostly unsorted and unstratified, matrix- supported bouldery debris-flow deposits that consist of granule- to boulder-size clasts in a sandy, silty sand, or finer-grained matrix. Unit locally includes poorly to moderately well sorted, crudely stratified, clast-supported, stream-deposited sand and gravel. These mass-movement and alluvial deposits commonly form fan-shaped landforms at the mouths of small tributaries streams. Locally these deposits coalesce to form a broad, relatively gently sloping apron. Clasts are mostly subangular to subrounded; some are as long as about 2 m, but most are much smaller. Unit Qf is commonly graded to levels at or slightly above present stream level. Depositional processes were periodically active during the Holocene, but probably were most active during Pinedale deglaciation. Surface is locally veneered by unmapped deposits of sheetwash alluvium and probably by hyperconcentrated-flow deposits. Fan deposits on the east side of the Arkansas River, in the southern part of the map area, are locally mantled by unmapped deposits of eolian sediments and alluvium undivided (Qes). Estimated thickness is as much as 15 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: Fan deposits. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Photographs near this crag
Taken within 1.5 km of this crag's map point and published under a licence that lets us show them, from Wikimedia Commons. The coordinates say where the camera was, not what it was pointed at, so some of these will be the creek or the trail rather than the rock.

Access & safety
The map point for this crag is on land managed by San Isabel National Forest (federal). It lies inside wild and scenic river, national forest.
The boundary is close. Land managed by Colorado Parks & Wildlife or Bureau of Land Management 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.
Rules for all Pike-San Isabel National Forests land
- Fees
- No entrance fee for the Pike-San Isabel National Forests or the Cimarron and Comanche National Grasslands. Fees apply at campgrounds and day-use areas operated by the forest's concessionaire, paid on site.
- Overnight
- On the Leadville, Salida and San Carlos districts of the San Isabel, camping at any location within the same 20-mile radius for more than 14 days in a continuous 30-day period is prohibited. No camping within 100 feet of water outside a developed or designated site.
Read on Pike-San Isabel National Forests'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.
