Ryan Flat dominates this high-desert landscape in Presidio County, Texas, during the mid-1970s and early 1980s. The terrain is defined by the steady transit of the Southern Pacific railroad, which cuts diagonally across the arid plains. At the small railroad siding of Aragon, the map records a bench mark and a cluster of structures that served this remote transit point. The geography here is sparse but functional, characterized by essential water sources like Well and Tank sites that sustained ranching or rail operations. To the northeast, the topography becomes more complex as the land drops into Big Trestle Draw, where a railroad trestle crosses the drainage. Evidence of local utility and transport is seen in a lone Gravel Pit and a remote Landing Strip, illustrating how people and materials moved through this expansive West Texas corridor.
