Thunder Basin National Grassland encompasses this high plains landscape of Weston County, where the settlement of Pedro sits along the southern rail line. The terrain is defined by deep draws and canyons, including Blacktail Canyon and Crane Canyon, which channel seasonal water toward the drainage of Skull Cr. Small-scale water management is evident through features like the Y T Reservoir and Bernard Howell Reservoir, essential markers of ranching history in this arid environment.
