1988 Map of Mexican Hat SE

About this map

Navajo Indian Reservation lands dominate this late-20th-century topographic survey, revealing a landscape defined by dramatic geological formations and seasonal watercourses. The prominent uplift of Comb Ridge runs through the eastern portion of the quadrangle, creating a striking visual boundary against the surrounding desert floor. Arid drainage patterns are clearly mapped, with Halgaitoh Wash, Gypsum Creek, and Cane Valley Wash cutting through the terrain. Evidence of localized water sources and resource exploration appears in the form of a solitary spring and a Well Drill Hole, while shifting Sand Dunes highlight the active environmental forces at work. This provisional map, compiled from mid-1980s aerial photography, provides a detailed record of the physical geography and sparse infrastructure in this corner of San Juan County.
