Belt Creek carves a winding path through the center of this landscape, creating a series of dramatic bends that necessitated complex engineering for transit. The presence of numbered structures such as Lacey Tunnel Number 3, Amphitheater Tunnel Number 4, and Belt Creek Tunnel Number 5 indicates a significant rail or road corridor following the river's descent. Settlement is concentrated at the small community of Waltham and the locality of Rogers, while the surrounding terrain is defined by distinctive coulees and heights like Shepherd Butte and Rattlesnake Hill. The map also documents local aviation infrastructure with the Peterson Ranch Airport situated near Highwood Creek. This 2017 survey details the intersection of Chouteau and Cascade counties, showing how modern transportation routes like Waltham Road and Highwood Road navigate the area's deep drainages and ridges.
