1992 Map of Encino

About this map

Alta Mesa Oil Field and the Strong Oil Field dominate the landscape of the South Texas brush country in the early 1990s, where the boundaries of Brooks, Jim Hogg, Starr, and Hidalgo counties converge. The region is characterized by a pattern of traditional ranching settlements and energy extraction, with many locations such as Agua Nueva and San Antonio Viejo reflecting long-standing Spanish and Mexican land grant histories. Transport follows a distinct north-south corridor through Encino and Rachal, where the rail line passes through Linn Siding. To the southeast, the hypersaline lake Sal del Rey sits as a notable geological landmark, a site harvested for salt since the colonial era. The map details a complex network of ephemeral drainages, including Viboras Creek and Arroyo Grande, which cut through the sandy plains toward the Laguna Madre beyond the sheet's edge.
