Rock, from the geologic map
Granodiorite of Mount Harvard. Mesoproterozoic, about 1,600 to 1,000 million years old.
Gray, medium-grained to coarse-grained, equigranular to porphyritic, weakly foliated biotite granodiorite at and near Mount Harvard. Composed, in decreasing amounts, of sodic plagioclase, perthite, quartz, biotite, chloritized biotite, opaque minerals, and minor amounts of apatite and zircon (Fridrich and others, 1998). Previously mapped as Paleoproterozoic Denny Creek Granite (Fridrich and others, 1998), but new U-Pb zircon age of 1,414±20 Ma (Moscati and others, 2017) indicates that this pluton is of Mesoproterozoic age
This is the map unit under this crag's map point, read from the 1:100,000 sheet (Kellogg and others, 2017, U.S. Geological Survey Scientific Investigations Map 3382). 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: Granodiorite of Mount Harvard. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Access & safety
The map point for this crag is on land managed by San Isabel National Forest (federal). It lies inside wilderness area, national forest.
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.

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.
