The international border between the United States of America and Mexico bisects this 1990s survey, illustrating the cross-border landscape where Pima County meets Sonora. Much of the northern terrain is occupied by the Tohono O'odham Indian Reservation, a region defined by its arid basins and the prominent rise of Morena Mountain. Small outposts like El Represito and the southern C. Jacobo suggest the sparse, isolated nature of settlement in this desert corridor.
