1979 Map of McCutchen Ranch

About this map

The Rio Grande Rio Bravo carves a winding path along the international border in this 1970s survey, anchoring a remote landscape where water and terrain dictate life. Small settlements like Buenavista and the Mc Cutchen Ranch appear near the river’s edge, while the higher elevations of the Sierra Los Fresnos dominate the western horizon. This map captures a specific moment in border history, documented shortly after the International Boundary and Water Commission's Treaty of 1970 revised the line.
