Several small cliff-houses occur in Sand Canyon, one of the northern
tributaries of the McElmo. Stone Arch House, here figured (pl. 6, _a_),
so-called from the eroded cliff (pl. 4, _b_) near by. It is situated in
the cliff, about a mile from where the canyon enters the McElmo Canyon
near Battle Rock. Abundant piñon trees and a few scrubby cedars grow
in the low mounds of the talus below the ruin, near which, on top of a
neighboring rock pinnacle, still stand the well-constructed walls of a
small house (pl. 4, _a_).
