About this map

The Big Snowy Mountains dominate this section of Golden Valley County, where the high-altitude terrain of the Lewis & Clark National Forest transitions into the coulee-cut plains below. The landscape is defined by dramatic elevation changes, notably at Knife Blade Ridge and Lost Peak. Water sources are vital markers in this arid environment, with drainage patterns following Swimming Woman Cr and the intermittent Dry Coulee.

A network of rural routes, including Swimming Woman Rd and Rothie May Rd, provides access to the lower gulches. Named landmarks like Wrzesinski Coulee and Huffman Gulch suggest a history of early land use and local family naming conventions. The map also identifies specific water points such as Merrills Spring, which served as critical infrastructure for the ranching operations that have long characterized this part of Montana.
