How well located

Position on wall known 40 

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 Creek Beach, BB8, Lady of the Right (3 climbs, about 90 seconds on Corona Crag) would place up to 18 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

Castle Rock Conglomerate. Rupelian, about 30 to 29 million years old.

Indurated bouldery cobbly gravel composed mostly of Precambrian rocks exposed in the Front Range, but also contains some chert and Tertiary volcanic rocks. The sandy matrix of the conglomerate is well-cemented by silica, but basal part of deposits locally is less cemented and softer than the main part of the formation. Generally less than 15 m thick. In eastern part of mapped area includes mudstone, claystone, siltstone, and sandstone that contain volcanic ash.

This is the map unit under this crag's map point, read from the 1:100,000 sheet (Trimble and others, 2003, U.S. Geological Survey Geologic Investigations Series I-856-H). 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: Castle Rock Conglomerate. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

On the map since 1894

The USGS has mapped this ground since 1894. 28 historical sheets cover this crag's map point; the oldest is below.

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 39.37862 N, 104.79787 W (Mitchell Creek Canyon). That point can be off by hundreds of metres, so say so.

We don't know who manages this ground: PAD-US doesn't map this point as protected land, which most often means it is private. Find out whose it is before you go.

Nobody has yet read the land manager's own rules for this crag and written them down here, so treat the above as where you are, not as what you may do.

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.
