1984 Map of Flattop Mtn

About this map

Flattop Mtn dominates this 1984 topographical survey of San Bernardino County, where the high desert landscape is defined by resource extraction and sparse water management. The area shows evidence of industrial and survival infrastructure, including the Rex Mine and a specialized Guzzler system for capturing runoff. Human presence is concentrated at Browns Camp and around the Hacienda area, while a series of underground pipelines and a dike suggest the critical importance of water transport in this arid environment. The map details a network of 4wd tracks and multiple lanes that cut through the desert terrain, providing access to remote points like the Natural Water Tank and Flattop Mtn Spring. To the southeast, the terrain shifts into the higher elevations of Eagle Peak and the navigable Eagle Pass, illustrating the difficult passage through the eastern San Bernardino range.
