2020 Map of Posy Valley
USGS Topo · Published 2020About this map
Pine Valley and the surrounding high-desert landscape define this portion of the borderlands near the Snake River. The map documents a complex irrigation network essential for ranching and agriculture in this arid environment, featuring the McMullen Ditch and the Posy Valley Ditch, which channel water across the terrain to numerous storage sites like Laird Reservoir and Densley Reservoir. These water management features, alongside named landforms like The Saddle and Timber Canyon, illustrate the human effort to adapt to the valley's geography.
