Rock, from the geologic map

Leadville Limestone, Williams Canyon Limestone , Manitou Limestone, and Sawatch Quartzite (Leadville Limestone, Williams Canyon Limestone , Manitou Limestone, Sawatch Quartzite) — limestone, minor quartzite. Paleozoic, about 508 to 337 million years old.

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: Leadville Limestone, Williams Canyon Limestone , Manitou Limestone, and Sawatch Quartzite. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

On the map since 1927

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 E (USGS elevation). Shade from the surrounding terrain is counted.
Deep terrain: the skyline averages 24° 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 39.57235 N, 107.25545 W (Grizzly Creek Wall (aka Mudwall)). That point can be off by hundreds of metres, so say so.

The map point for this crag is on land managed by White River National Forest (federal). It lies inside national forest.

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.

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.
