The Tongue River meanders through this portion of Pembina County, connecting the small agrarian communities of Akra and Backoo with the regional hub of Cavalier. The landscape is defined by the rigid precision of the Public Land Survey System, with a dense grid of gravel roads like 98th St NE and 138th Ave NE carving the prairie into productive agricultural sections. In the southeast, Cavalier serves as the focal point of local governance and transportation, anchored by the Pembina County Courthouse. The area’s aviation history is visible through both the Cavalier Municipal Airport and the smaller Hinkle Airport to the west. This modern survey captures a landscape where the primary drainage of the river provides the only deviation from a perfectly gridded network of section lines and township boundaries like t162n r54w.
