What's here
5.7 to 5.13, mostly around 5.11.
Counted from the 37 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 37
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 Unnamed Dihedral, Vergin' on Perversion, Red Dihedral, Oblique Streak (4 climbs, about 120 seconds) would place up to 33 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
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. The rock named at the top of this page comes from the public geology of this area; this card is the map's answer. 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

Access & safety
The map point for this crag is on land managed by City of Boulder Open Space and Mountain Parks (local government), in Eldorado Mountain (Conda Quarry).
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.

Nearby, from OpenStreetMap
- Toilets
- 1,414 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.
