1966 Map of Two Grey Hills

About this map

Two Grey Hills and the surrounding high desert of the Navajo Indian Reservation are documented here through 1965 aerial photography and a 1966 field check. The landscape is defined by its drainages, notably Captain Tom Wash and Tuntsa Wash, which cut through a terrain of plateaus and ridges including the prominent Grey Mesa. Evidence of human presence and survival in this arid environment is indicated by a Cem and water sources like Mormon Spring and a simple Spring. The topography reveals a network of unimproved dirt roads and trails that traverse the hills, connecting isolated points across the open range. This survey, published by the Geological Survey in 1978, provides a precise look at the land's natural contours and sparse landmarks prior to modern development.
