Huntley Coulee and Portage Coulee carve through this high-plains landscape where the Chouteau Co Cascade Co border bisects the terrain. The map captures the agricultural and industrial layout of the mid-1960s, anchored by the Great Northern railroad line and the small settlement of Portage. This area is defined by its water sources and infrastructure, featuring Twenty-eight Mile Spring, Flick Lake, and an extensive Pipeline network. Rural life and education are centered at the Roosevelt Sch, while local industry is evidenced by numerous Gravel Pits and the remote Whitehorn siding. The presence of Dent Bridge Road provides a primary north-south artery for this ranching and transport corridor, illustrating how mid-century infrastructure adapted to the natural drainage patterns of the Great Northern Coulee system.
