The Oregon Short Line railroad corridor dictates the settlement pattern of this Montana landscape, running parallel to the Red Rock River through the heart of the valley. The small community of Dell serves as a central point for local transportation, supported by the nearby Dell Flight Strip and the Big Sheep Creek Bridge. This 2020 survey illustrates how modern infrastructure follows the same natural routes established by early pioneers and rail engineers, with the W Side Frontage Rd and Interstate system tracing the historic path toward the Continental Divide.
