St. Marie anchors the southwestern edge of this northern plains landscape, situated near the headwaters of the winding Porcupine Cr. The terrain is characterized by the distinct drainages of Porcupine Valley and the neighboring Calderwood Hills to the east. This 2014 survey reveals a sparsely populated region of Valley County where water management is critical to the local geography, evidenced by the central Middle Reservoir and natural water sources like Olson Springs and Potter Spring.
