Rock, from the geologic map

Landslide deposits. Quaternary, younger than 781,000 years.

Slumps, debris flows, earthflows, rockfall avalanche deposits, and similar large masses of locally derived debris moved downslope by gravity.

This is the map unit under this crag's map point, read from the 1:100,000 sheet (Trimble and others, 2003, U.S. Geological Survey Geologic Investigations Series I-856-H). 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: Landslide deposits. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Photographs near this crag

Taken within 1.5 km of this crag's map point and published under a licence that lets us show them, from Wikimedia Commons. The coordinates say where the camera was, not what it was pointed at, so some of these will be the creek or the trail rather than the rock.

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 39.68168 N, 105.21084 W (The Broadway Boulder). That point can be off by hundreds of metres, so say so.

The map point for this crag is on land managed by Jefferson County Open Space (local government), in Matthews/Winters Park. It lies inside local 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.

Rules for all Jefferson County Parks & Open Space land

Climbing permit
Installing fixed hardware on a new route requires a permit: a Fixed Hardware Application, vetted by the Fixed Hardware Review Committee before the Climbing Committee decides.
Hours
Unlawful to be on Open Space land from one hour after sunset to one hour before sunrise, unless posted otherwise.
Rules
JCPOS does not install, maintain or inspect hardware related to rock climbing. Climbing ethics differ by park -- Clear Creek Canyon, the Cathedral Spires and the South Platte each have their own published guidelines.
Overnight
Camping by advance permit only, obtained online at least 24 hours ahead -- not at the park, headquarters or by phone. Only White Ranch and Reynolds Parks, tent-only.
Dogs
Dogs must be on a leash ten feet or less in length and under physical control.

Read on Jefferson County Parks & Open Space'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.

Toilets

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.
