How well located

Position on wall known 10 

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 Sam's Spam, 3D Puzzle Master (2 climbs, about 60 seconds) would place up to 8 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

Dolores Fm and Cutler Fm (Dolores Formation, Cutler Formation) — siltstone, sandstone, conglomerate. Phanerozoic, about 299 to 222 million years old.

Red siltstone, sandstone, and conglomerate

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: Dolores Fm and Cutler Fm. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Photos from climbers

No photos here yet. If you're at the crag, yours would be the first.

Pick a photo from your camera roll rather than taking one here: a picture taken inside a browser usually has no location saved in it, and we check that the photo was taken at this crag before publishing it. Photos of guidebook pages and topos are refused — they're the author's work. By sending one you're letting us publish it.

Nobody reviews these before they appear, so anyone can report one and it's hidden straight away — including you, if you change your mind, and including a photographer who finds their own picture here.

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.

Wall faces SW (USGS elevation). Shade from the surrounding terrain is counted.
Deep terrain: the skyline averages 21° above horizontal, so the sun has to climb well clear of the rim before it reaches this wall.

Access & safety

Emergency: call 911. Read out your location: Works without signal. If GPS fails, this crag's approximate map point is 38.11410 N, 107.71790 W (Ridgway Dike Wall). That point can be off by hundreds of metres, so say so.

The map point for this crag is on land managed by Bureau of Land Management (federal), in Uncompahgre 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.

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.
