About this map

The town of Beaver serves as the focal point of this 1980s-era survey, where the valley's agricultural infrastructure meets the rising elevations of the Fishlake National Forest. A complex network of irrigation systems, including the South Field DITCH, Willis Ditch, and Harris Ditch, reveals the vital importance of water management for the high-desert landscape. The terrain shifts from the flat Table Grounds and Last Chance Bench into the significant verticality of Black Ridge and Black Mountain.

Evidence of early-to-mid-century recreation and utility is prominent, with a Golf Course Race Track and Athletic Field situated near the town center, while a Power Plant and Substation indicate the region's energy development. Further east, the landscape is defined by deep drainages like Sway Hollow and Merchant Hollow that feed toward the Beaver River. Higher elevations include peaks like Rattlesnake Peak and Johnson Peak, as well as localized spots like Ponderosa Park and Little Cottonwood Campground.
