Rock, from the geologic map

Minturn Fm in west-central and south-central and other units (Minturn Formation) — arkose, conglomerate, shale, minor limestone. Pennsylvanian, about 312 to 306 million years old.

Arkosic sandstone, conglomerate, shale, and limestone. Includes Madera Fm and Sharpsdale Fm of Chronic (1958) in Sangre de Cristo Range and Gothic Fm of Langenheim (1952) in Elk Mountains. Other units of Middle Pennsylvanian age.

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: Minturn Fm in west-central and south-central and other units. 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.

Access & safety

Emergency: call 911. Read out your location: Works without signal. If GPS fails, this crag's approximate map point is 39.61901 N, 106.43861 W (Lower Canyon). That point can be off by hundreds of metres, so say so.

The map point for this crag is on land managed by Colorado Parks & Wildlife (state), in Vail Deer Underpass State Wildlife Area. It lies inside state conservation area.

The boundary is close. Land managed by White River National Forest 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 Colorado Parks & Wildlife land

Fees
Every Colorado state park requires an entrance pass for motor vehicles. A daily vehicle pass is $4 to $17 depending on the park; an individual pass covers entry on foot or bike.
Reservations
Eldorado Canyon runs timed-entry vehicle reservations on summer weekends and holidays; see the park's own page. Other parks do not require one to enter.
Permits
A daily pass is valid until noon on the day after purchase. The annual Keep Colorado Wild pass is $29 and is bought with a vehicle registration.

Read on Colorado Parks & Wildlife'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

Toilets
1,057 m away (map)

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.
