Big Porcupine Creek and its many seasonal tributaries define the drainage patterns of this high-plains landscape in Rosebud County. The terrain is characterized by deep erosional features including Hallanger Coulee and the colorfully named Wild Horse Pete Coulee. Human presence is sparse, marked primarily by a grid of rural roads such as Acorn Flats Rd and Cohagen Rd that navigate the sections between the creek beds.
