Rock, from the geologic map
Fountain Formation. Paleozoic, about 323 to 273 million years old.
Maroon and red, arkosic, thick-bedded, coarse-grained to pebbly, cross-bedded fluvial sandstone and conglomerate containing thin layers of dark-maroon, hard (siliceous), micaceous siltstone and silty, fine-grained sandstone. Coarser beds commonly fill shallow channels. Sandstone locally bleached light tan to white. Clasts are well rounded to subrounded, as long as 25 cm, and composed mostly of Proterozoic rocks. Scott (1972) reported rare lower Paleozoic clasts in lower part of formation in Morrison 7.5-minute quadrangle. Thickness in quadrangle about 600 m; in Eldorado Springs quadrangle a measured section is 305 m thick (Wells, 1967). Mapped only in Denver Basin
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: Fountain Formation. 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.

Access & safety
The map point for this crag is on land managed by Jefferson County Open Space (local government), in Matthews/Winters 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.
Rules for all Jefferson County Parks & Open Space land
- Climbing permit
- Installing fixed hardware on a new route requires a permit: a Fixed Hardware Application, vetted by the Fixed Hardware Review Committee before the Climbing Committee decides.
- Hours
- Unlawful to be on Open Space land from one hour after sunset to one hour before sunrise, unless posted otherwise.
- Rules
- JCPOS does not install, maintain or inspect hardware related to rock climbing. Climbing ethics differ by park -- Clear Creek Canyon, the Cathedral Spires and the South Platte each have their own published guidelines.
- Overnight
- Camping by advance permit only, obtained online at least 24 hours ahead -- not at the park, headquarters or by phone. Only White Ranch and Reynolds Parks, tent-only.
- Dogs
- Dogs must be on a leash ten feet or less in length and under physical control.
Read on Jefferson County Parks & Open Space'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
- 480 m away (map)
- Mapped parking
- 577 m away, 58 spaces (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.
