1986 Map of Washington Dome

About this map

Fort Pearce (Site) anchors the southern reaches of this landscape where the Fort Pearce Wash winds through the high desert. This 1980s provisional survey illustrates the geographic transition from the Virgin River and the engineered Washington Canal in the north to the distinctive geological formations that dominate the central terrain. Prominent landmarks such as Shinob Kibe, Washington Dome, and Punchbowl Dome provide clear vertical reference points across a region defined by Warner Ridge and the broad expanse of Warner Valley. The map also details the northeastern edge of Sand Mountain, highlighting a rugged topography of dunes and ridges that shaped early transit and settlement patterns along the Utah-Arizona border. Local industry is briefly noted at the Gravel Pit near the river, while natural water sources like Warner Valley Spring suggest the critical role of water management in this arid environment.
