Counted from the 7 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 7 

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 Hardman Jr., The Vanderslice (2 climbs, about 60 seconds) would place up to 5 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

Boulder Creek granodiorite. Paleoproterozoic, about 2,500 to 1,600 million years old.

Gray, coarse-grained, equigranular to porphyritic, massive to weakly foliated biotite±hornblende±muscovite monzogranite, granodiorite, and tonalite. Forms large intrusive body (Boulder Creek batholith) west of Boulder (Gable, 1980). Typically weathers into grayish-tan rounded outcrops. Mean U-Pb zircon date from numerous analyses is 1,716±3 Ma (W.R. Premo and K.S. Kellogg, unpub. data, 2007), which supports earlier U-Pb zircon dates of 1,725 Ma (Stern and others, 1971) and 1,721±15 Ma (Premo and Fanning, 2000)

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: Boulder Creek granodiorite. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

On the map since 1899

The USGS has mapped this ground since 1899. 25 historical sheets cover this crag's map point; the oldest is below.

Photos from climbers

No photos here yet. If you're at the crag, yours would be the first.

Pick a photo from your camera roll rather than taking one here: a picture taken inside a browser usually has no location saved in it, and we check that the photo was taken at this crag before publishing it. Photos of guidebook pages and topos are refused — they're the author's work. By sending one you're letting us publish it.

Nobody reviews these before they appear, so anyone can report one and it's hidden straight away — including you, if you change your mind, and including a photographer who finds their own picture here.

Taken at the crag by climbers and published as they sent them. Each one's own location had to be within 0.5 km of this crag before we accepted it. See something that shouldn't be here? Use Report this photo under it and it's hidden at once. Anything else, write to us.

Access & safety

Emergency: call 911. Read out your location: Works without signal. If GPS fails, this crag's approximate map point is 39.93140 N, 105.42090 W (The Main Pinecliffe Crag). That point can be off by hundreds of metres, so say so.

The map point for this crag is on land managed by Boulder County, CO (local government), in Williamson-Jacoby.

The boundary is close. Land managed by Roosevelt National Forest 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.

Worth checking first. PAD-US records public access to this unit as “closed” (according to NCED, 2023). That is about getting onto the unit at all, not about climbing, and we have not checked it against Boulder County, CO's own page.

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.

Nobody has yet read Boulder County, CO's own rules for this crag and written them down here, so treat the above as where you are, not as what you may do.

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.
