1986 Map of St. George

South of the main settlement, the topography transforms into a series of benches and washes, including the Price City Bench and Fort Pearce Wash. The map documents the vital role of irrigation and land use in this desert environment, from the agricultural Washington Fields to the Sewage Disposal Plant near the river. Along the southern border, the transition into Big Valley marks the boundary between Utah and Arizona, where the rugged terrain of White Dome rises above the drainage of Atkinville Wash.
