About this map

Portales Valley defines the lower third of this West Texas and New Mexico borderlands survey, where the low-lying terrain gives way to the characteristic depressional basins of the Llano Estacado. The landscape is marked by the straight-line geometry of the Public Land Survey System, specifically townships t1s r37e and t2s r37e, which dictate the local grid of rural corridors. The map records the precise boundary where New Mexico meets Texas, a line followed closely by S Roosevelt Road A. While mostly open country, the map identifies a network of essential county and farm-to-market routes, including Blackwater Rd and Fm 1760, which facilitate movement across the Roosevelt and Bailey County line.
