How well located

Position on wall known 13 

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 Mirage, Lean Left or Right (2 climbs, about 60 seconds on Oasis Boulder) would place up to 4 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

Hornfels. Late Cretaceous, about 100 to 66 million years old.

Dense, black hornfels and metasandstone in window of Williams Range thrust near Keystone; Pierre Shale metamorphosed by nearby Eocene Montezuma stock. Bedding is preserved at most locations

This is the map unit under this crag's map point, read from the 1:100,000 sheet (Kellogg and others, 2008, USGS Geologic Investigations Series 3000). 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: Hornfels. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

On the map since 1924

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.

Sun today
sun 09:40-16:20
Wall faces SW (USGS elevation). Shade from the surrounding terrain is counted.
Deep terrain: the skyline averages 18° 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 39.60936 N, 105.91708 W (Oasis Boulder Area). 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 inventoried roadless area, 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.
