About this map

The dissected rangelands of the Northern Plains are mapped here along the border of Phillips and Valley Counties. This 1984 provisional map documents a network of seasonal drainages and coulees that feed into Larb Creek, which snakes through the eastern half of the quadrangle. The terrain is characterized by a series of numbered waterways including Second Creek, Third Creek, and Fourth Creek, indicating a systematic naming convention used by early settlers or surveyors in this part of Montana.

Key landmarks for navigation in this arid landscape include the elevated Spencer Point and the essential water source at Christmas Reservoir. Smaller topographic features like McNab Coulee and Hadley Coulee illustrate the intricate erosion patterns of the Missouri River break country. The presence of Pack Rat Coulee and Dead Horse Coulee provides a glimpse into the local nomenclature of the ranching era, marking specific corners of the range used for livestock and transit.
