The international border between the United States of America and Mexico bisects this arid landscape, showing the transition from the Tohono O'odham Indian Reservation in Pima County to the northern reaches of Sonora. The northern portion is defined by the Great Plain, a wide expanse marked by isolated settlements like El Tupil and L. Sucita Viejo situated near the boundary line.
