1916 Map of Eagle Mountain

About this map

Military reconnaissance and civilian ranching life intersect along the Rio Grande in this 1916 survey. Topography from the Sierra De Los Pinos and Eagle Mt. dominates the landscape, where water sources like Loves Spring and Frenchmans Well were critical for both the cavalry and local cattlemen. The map documents a specific period of heightened security, noting the presence of Troop B 15th Cav. and Squadron positions. Ranching outposts such as McCameys Ranch, Dominees Ranch, and the Bosque Bonito (T.O. Ranch) are meticulously recorded alongside infrastructure like ranch gas pumps. Strategic river access is marked at the Troop A Crossing, reflecting the era's operational focus on the border during the Mexican Revolution. Geographers also noted terrain landmarks such as Castle Rock and the high peaks of Las Vacas, providing a clear view of the high-desert environment before modern development.
