1966 Map of Thompson Arroyo

About this map

Thompson Arroyo and a series of rugged watercourses carve through the southeastern Colorado high plains along the boundary of Otero and Bent Counties. This 1960s landscape is defined by its drainage systems, featuring the Vandiver Arroyo, Robinson Arroyo, and the East Fork of the King Arroyo. Human activity in this arid environment is focused near the northern corner, where a Drive-in Theater and a Gravel Pit appear alongside a prominent Pipeline. Further south, the terrain rises toward Miller Mesa, where Circle I Waters Spring provides a rare named water source amidst the canyons. This map offers a detailed view of the regional ranching and transport infrastructure before modern consolidation, marked by landmarks like a Radio Tower and the deep winding path of Mixon Canyon.
