Big Valley dominates the central landscape of this 2011 survey, showing a remote stretch of the Arizona-Utah border region defined by ephemeral water sources and high desert terrain. The arid character of the land is highlighted by the distribution of critical water points such as Lizard Spring, Mokaac Spring, and the North Tank. While County Hwy-5 provides the primary north-south transit corridor through the valley floor, the surrounding topography rises sharply to landmarks like Mokaac Mountain and Little Black Mountain. Human modification of this dry environment is evident in the presence of the State Line Reservoir and Mokaac Reservoir, which likely serve as vital stock ponds or catchment basins for local ranching operations. The drainage patterns of Mokaac Wash and Quail Canyon further illustrate the rugged watershed systems that shape this borderland territory south of St. George.
