Forsan and the neighboring settlement of Ross City anchor this West Texas landscape, shaped by the enduring presence of the energy industry. The Howard Glasscock Oil Field dominates the central portion of the quadrangle, with a network of access roads like Ranch Road 821 and McDonald Rd N providing the primary infrastructure for the area's oil operations. The terrain is defined by natural drainage patterns, most notably the upper reaches of the N Concho River and the uniquely named Cannibal Draw which carves through the southern landscape. Smaller watercourses such as Bull Cr and Dobson Cr flow through the eastern and northern reaches, respectively. This survey captures a moment in the early 21st century where the traditional grid of city streets like Avenue A and 1st St in Forsan meets the sprawling, industrial layout of the surrounding Permian Basin oil fields.
