Williams Prairie and the surrounding high-elevation grasslands of Crook County define this landscape as it appeared in the early 21st century. This region of the Ochoco National Forest is characterized by extensive meadows and prairies, including Big Summit Prairie and Antler Prairie, which have historically served as critical grazing lands. The map details the water management infrastructure essential for this arid environment, showing the Peterson Creek Dam creating the Peterson Creek Reservoir, alongside the Gili Reservoir and its associated Gili Ditch.
