I call this the "alcove outcrop" because an alcove (not visible here) has been eroded in it.
The outcrop lies at the center of this WikiMapia aerial view (click on any rectangle for
information): http://www.wikimapia.org/#lat=38.74862&lon=-109.498909&z=18&l=0&m=a&v=2 .
The next photo shows the outcrop's wall up close.
