Cerro el Gallo is one of the smaller Chihuahuan cerros de
trincheras and has not yet been investigated carefully. The ring
at the top of this hill is about 50 meters in diameter, and the
constructions here are less extensive than those at Cerro Juanaqueña
and Cerro Vidal. A brief field inspection here also suggests that
this hill was not used as intensively as the other two. On all
three sites the stone work was created by removing loose rocks
from the surface of the hill and piling them into long windrow-like
piles referred to here as walls. On steeper slopes the loose surface
rocks were pushed downslope to form lobe-shaped terraces.
