a corral with animals

The detail appears to be a fenced area, perhaps a corral, containing sheep or goats (as suggested by Richard Conway). A hut and perhaps some vegetation also appear nearby, and a road goes past the animals and the small building on their east side. This detail appears to be located on the slope of the mountain range (Sierra de Santa Catarina?) to the north of San Pedro Tlahuac and neighboring communities. [SW]
