About this map

The Rio Grande defines the international boundary in this part of Cameron County, weaving through a landscape of agricultural tracts and residential colonias. The map documents the intricate settlement patterns of the borderlands, including Angel Haven Colonia, Valle Hermosa Colonia, and Alabama-Arkansas Colonia. These communities are situated among larger landholdings such as English Farms and Nogales Ranch, reflecting the region's mix of rural residential development and traditional ranching.

Several banco locations, such as Los Borregos Banco Number 123 and La Canasta Banco Number 4, mark segments of land historically affected by the river's shifting course. Local history is further grounded at the Southmost Cemetery and the Southmost Ranch, while the name Palm Grove alludes to the distinct vegetation of the lower valley. This survey captures the road network connecting these areas, including Southmost Rd and Sabal Palm Grove Rd, providing a detailed view of the infrastructure at the southernmost edge of Texas.
