5.6 to 5.10, but over half of these routes are 5.9.
Counted from the 5 climbs here that carry a grade. Shown only where there are at least 5 of them — below that the shape is noise.

Rock, from the geologic map
Boulder Creek Granodiorite — intrusive igneous (plutonic). Paleoproterozoic, about 2,500 to 1,600 million years old.
Light- to medium-gray, medium- to coarse-grained, weakly to strongly foliated granodiorite composed of oligoclase, quartz, microcline, and 5-15 percent biotite; phenocrysts of microcline (1-4 cm long) common. Forms a large elongate pluton in south-central part of map area, and small bodies 4 km northeast of Lake Estes, 1 km east of Lead Mountain (Never Summer Mountains), and in southeast corner of map area. Rb-Sr age for Boulder Creek Granodiorite in plutons southeast and northeast of map area is 1,664+/-40 Ma (Peterman and others, 1968, p. 2287). GRI Source Map ID 141 (I-1973). ** Areas where numerous dikes of Silver Plume Granite (Ysp) intrude Boulder Creek Granodiorite [indicated by stippled regions on source paper map].
This is the map unit under this crag's map point, read from the 1:100,000 sheet (National Park Service Geologic Resources Evaluation program, 2006, National Park Service). 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: Boulder Creek Granodiorite. 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 National Park Service (federal), in Rocky Mountain National Park. It lies inside wilderness area, national 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.

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.
