About this map

Willamar Oil Field dominates the central landscape of this Willacy County coastal plain, illustrating the industrial footprint of petroleum extraction in south Texas. The area is defined by a grid of rural roads and scattered ranching operations, including the notable El Sauz Ranch to the north and El Sabinito Ranch at the southern boundary. These large landholdings are punctuated by livestock water sources such as Sacatosa Tank and Retamita Tank, which were essential for managing cattle in this semiarid environment.

Local history is preserved in small communal hubs like Willamar Camp and the settlements of Willamar and Porfirio. Genealogists and researchers can find specific points of interest in the El Toro Cemetery and La Jarita Cemetery, which serve as quiet markers of the families who settled this region. The infrastructure, consisting of routes like FM 1420 and Old Alice RD, connects these isolated ranches and oil operations to the broader Rio Grande Valley trade network.
