Uhlan Coulee and the surrounding drainage basins of Valley County define this northern Montana landscape. The area is characterized by a series of deep erosional features including Johnson Coulee and Enright Coulee, which channel seasonal water toward Porcupine Cr and the wider Porcupine Valley. These landforms dictate the placement of local transport routes like Spring Coulee Rd and Sargent Creek Rd, which navigate the high ground between the various forks and tributaries.
