Rock, from the geologic map
Rocks of Montezuma stock and vicinity, older felsic to intermediate porphyries of alkali-calcic group. Phanerozoic, about 100 to 56 million years old.
Large stocks, adjacent smaller bodies, and dikes in Nederland area and in southern Empire and northern Georgetown 7.5-minute quadrangles. Includes the Caribou, Bryan Mountain (also called Eldora), and Apex stocks. Includes monzogranite, monzogranite porphyry, biotite-hornblende±pyroxene monzogranite (Gable, 1969), and granodiorite (Ed Dewitt, written commun., 2007). K-Ar age of Caribou stock is 68.2±4.1 Ma on hornblende and 65.5±2.4 Ma on biotite (Marvin and others 1989). K-Ar age on Bryan Mountain stock is 60.6±1.8 Ma on biotite (McDowell, 1971; Marvin and others, 1974)
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: Rocks of Montezuma stock and vicinity, older felsic to intermediate porphyries of alkali-calcic group.

Photographs near this crag

Access & safety
The map point for this crag is on land managed by Roosevelt National Forest (federal). It lies inside national forest.
The boundary is close. Land managed by Boulder County Parks & Open Space 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 Arapaho and Roosevelt National Forests land
- Fees
- No entrance fee for the forest. Some locations require a reservation, pass, permit or day-use fee.
- Overnight
- Camping more than 14 days in a 30-day period, or more than 30 days in a 365-day period, is prohibited across the forests and the Pawnee National Grassland. Dispersed camping is within 300 feet of most Forest Service roads, on National Forest land; the MVUM shows which.
Read on Arapaho and Roosevelt National Forests'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.

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.
