About this map

The Missouri River forms a significant geographical and political boundary here, dividing Roosevelt Co and McCone Co in this section of northeastern Montana. The landscape transitions from the relatively flat river valley in the north to the intricately eroded coulees and breaks to the south. This rugged southern terrain is drained by several seasonal waterways, most notably Nickwall Cr, which meanders through the central and southern portions of the quadrangle.

Infrastructure is sparse, reflecting the rural character of the Wolf Point District. Primary access is provided by tribal and local routes such as BIA Rte 1 and Nickwall Rd. In the north, smaller drainages like Tule Cr and Chelsea Cr feed into the Missouri, while Bermley Cr appears in the far southeastern corner. The map documents the persistent township and range grid, including t27n r48e and t27n r49e, which historically governed land distribution in this Missouri River breaks country.
