1966 Map of Jumbo

About this map

Jumbo and Lambert anchor this section of the Texas Panhandle, recorded by the Geological Survey during the mid-1960s with revisions reflecting the late 1970s. The landscape is defined by the ephemeral drainage of Middle Tule Draw and a dense network of water wells, essential for the high-plains agricultural economy of the era. The survey captures the early industrialization of cattle ranching, marked by a significant Feedlot and the infrastructure of a power Substation. Spanning the boundary of Deaf Smith and Castro Counties, the map documents a transition from traditional land use to more intensive irrigation and livestock management, with fine red dashed lines indicating the specific layout of fence lines across the high plains.
