The Rio Grande forms a winding natural boundary along the southern edge of this Starr County landscape, where the United States Mexico border follows the river's deep curves. This military edition survey, revised from late 1920s aerial photography, reveals a region defined by large family pastures and extensive ranching operations. Significant settlements like La Grulla and Sullivan City sit along the Military Highway, which parallels the river. Inland, the map documents a network of named holdings including the Manuel Garcia Ranch and Stephen Garcia Ranch. The presence of the La Grulla Sta and a Brick Yard near the river indicates the localized industrial and transport hubs of the era. To the north, the terrain transitions into broad grazing lands such as Wells Pasture and Nicasio Solis Pasture, marked by occasional dry wells and isolated tanks.
