What's here
VB to V1, with no single grade dominating.
Counted from the 18 climbs here that carry a grade. Shown only where there are at least 5 of them — below that the shape is noise.
How well located
Position on wall known 22
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 Pisces Problems, Novid-91, Mushrooms and Chocolate Milk (3 climbs, about 90 seconds) would place up to 19 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.

Photographs near this crag
Taken within 1.5 km of this crag's map point and published under a licence that lets us show them, from Wikimedia Commons. The coordinates say where the camera was, not what it was pointed at, so some of these will be the creek or the trail rather than the rock.

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
The map point for this crag is on land managed by Douglas County (local government), in Rock Park. It lies inside local park.
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.
Nobody has yet read Douglas County'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.
Nearby, from OpenStreetMap
- Toilets
- 340 m away (map)
- Mapped parking
- 351 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.
