1985 Map of Flat Top Mesa

About this map

Bunkerville occupies the low-lying fertile ground along the south bank of the Virgin River in the mid-1980s, serving as a concentrated point of settlement amidst the arid high plateaus of the Nevada desert. This survey documents the critical irrigation infrastructure of the Virgin Valley, most notably the Bunkerville Ditch which traces the base of the bluffs to sustain local agriculture. The surrounding landscape is defined by the massive elevated landforms of Flat Top Mesa to the east and Mormon Mesa to the west, separated by the deep drainage of Toquop Wash. The boundary between Lincoln and Clark Counties crosses the northern portion of the sheet, where the terrain transitions from the river valley into dissected uplands and remote catchments like Sink Reservoir.
