Gu Vo Wash and San Simon Wash define the drainage patterns across this arid landscape in the Pisinemo District. As of 2011, the primary human infrastructure through this territory is Indian Rte 28, which cuts across the central portion of the quadrangle. The map reflects a largely undeveloped stretch of the Sonoran Desert, where ephemeral watercourses create a complex network of seasonal channels. This survey by the U.S. Geological Survey provides a precise view of the subtle topographic changes and elevation contours that dictate water flow in this remote part of Pima County.
