What's here
V0 to V10, with no single grade dominating.
Counted from the 35 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
Base placed (one source) 1 Position on wall known 27 Crag only 7
The order of the climbs along this wall is known from the open catalogue, so a few surveys go a long way: standing at Slopenstein, Pinchenstein, Golf Ball Right (3 climbs, about 90 seconds on Stein Boulder) would place up to 17 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
Maroon Fm (Maroon Formation) — arkose, siltstone, conglomerate. Paleozoic, about 323 to 270 million years old.
Arkosic sandstone, siltstone, conglomerate, and local limestone
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: Maroon Fm. 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.

Taken at the crag by climbers and published as they sent them. Each one's own location had to be within 0.5 km of this crag before we accepted it. See something that shouldn't be here? Use Report this photo under it and it's hidden at once. Anything else, write to us.

Access & safety
The map point for this crag is on land managed by White River National Forest (federal). It lies inside inventoried roadless area, national forest.
The boundary is close. Land managed by Pitkin County Open Space & Trails 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 White River National Forest land
- Rules
- The forest strongly recommends dispersed campers pack out solid human waste using an approved disposable or self-contained system rather than burying it in a cathole.
- Overnight
- Camping more than 14 days in any continuous 30-day period is prohibited, counted from the first day of occupancy. Some places allow dispersed camping only at designated sites and some run a shorter 7-day limit in summer.
Read on White River National Forest'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

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.
