On the floor of the Sonoran Desert in southwestern Arizona it is difficult to tell that it is Autumn in North America…however the crisp and dry autumn air creates a wonderful view of the abstract erosion as we look through the atmosphere. Rain is infrequent here and it is always a “gully washer” when it comes and makes its mark upon the desert. Ridges are revealed and deep grooves flow and spread amid the pinnacles of rock.
