2016 Map of Thompson Arroyo

About this map

Comanche National Grassland dominates the southern reaches of this landscape, where the high plains of Otero County meet the boundary of neighboring Bent County. This 2016 survey illustrates a terrain defined by a complex drainage network, characterized by deep-cut watercourses such as Thompson Arroyo and Rock Arroyo. The presence of the Old Otero Canal and Circle I Waters Spring points to the vital importance of water management in this arid cattle-ranching region. High ground is marked by prominent landforms like Miller Mesa, while the southern topography breaks into the secluded Mixon Canyon. The map provides a clear view of the rural road system, including Co RD Aa and Co RD 35, which follow the section lines of the Public Land Survey System to connect remote ranches and grazing lands.
