1984 Map of East of Leach Lake

About this map

The Avawatz Mountains dominate this high-desert terrain within the Fort Irwin Military Reservation. This 1984 provisional edition highlights a landscape shaped by topographic extremes and restricted military access in San Bernardino County. In the southern reaches of the quadrangle, Drinkwater Lake appears as a prominent hydrologic feature in an otherwise arid expanse. The map illustrates a network of 4wd tracks that serve as the primary means of navigating the complex slopes and valleys of the range, reflecting the area's use for tactical maneuvers and training during the late twentieth century. Surveyed between 1976 and 1981, this sheet documents the precise boundaries of the reservation as it stood before modern expansions.
