Rock, from the geologic map

Eocene prevolcanic sedimentary rocks (Echo Park Alluvium, Telluride Conglomerate, Blanco Basin Formation) — arkose, gravel, minor conglomerate, mudstone, sandstone. Paleogene, about 57 to 46 million years old.

South-central: Arkosic sand and bouldery gravel of Echo Park Alluvium. Southwest: includes Telluride Conglomerate and Blanco Basin Fm (arkosic mudstone, sandstone, and conglomerate)

This is the map unit under this crag's map point, read from the 1:500,000 sheet (Horton and others, 2017, U.S. Geological Survey Data Series 1052). 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 500 m wide on the ground, so the wall itself may be the neighbouring unit. Every crag on this unit: Eocene prevolcanic sedimentary rocks. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

On the map since 1897

The USGS has mapped this ground since 1897. 30 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 37.77579 N, 107.69569 W (Grand Turk). That point can be off by hundreds of metres, so say so.

We don't know who manages this ground: PAD-US doesn't map this point as protected land, which most often means it is private. Find out whose it is before you go.

Nobody has yet read the land manager'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.
