Porcupine Valley defines the southeastern portion of this map, where the winding Porcupine Creek is joined by tributary waters like Sargent Creek. This landscape is characterized by a network of drainage channels including Uhlan Coulee, Enright Coulee, and Johnson Coulee, which highlight the intricate hydraulic patterns of this part of Valley County. Human infrastructure in this rural area is represented by cattle-ranching and water-management features, most notably the Nyquist Number 2 Dam along the East Fork Cherry Creek. Named water sources such as Hermans Spring and Ericson Spring provide critical landmarks in a region largely defined by its natural geography and section-line roads like Geer Rd and Sargent Creek Rd.
