The evidence of extensive pastoral production along the margins of the pampa in Block 2 consist primarily of the structure bases from pastoral features along the margins of grazing area, primarily corrals, and associated artifact scatters. These pastoral facilities can be subdivided in terms of the size of the corral features and the apparent length of occupation based on artifact densities. Environmental characteristics do not help with isolating pastoral site groups, perhaps because the priority placed upon access to pasture dominates the site placement criteria. The mean slope of pastoral sites of various groupings in Block 2 is between 7-8°, and the most well-represented aspect for sites was the eastern aspect, accounting for 40 Block 2 sites.
