1958 Map of Roundup

About this map

Roundup serves as a focal point in this mid-century survey of Central Montana, where the Musselshell River corridor provides a lifeline for commerce and ranching. The landscape is defined by the dramatic rise of the Big Snowy Mountains and Little Snowy Mountains, areas protected within the Lewis and Clark National Forest. Water management is central to the region's development, evidenced by the Deadman's Basin Reservoir and the Yellow Water storage project. The Great Northern railroad dictates the pattern of settlement, linking small sidings and communities like Oka, Nihill, and Wallum. Evidence of the burgeoning energy sector appears near the river valley with several Oil Wells and Oil tanks, while the Hailstone National Wildlife Refuge marks the conservation efforts of the 1950s. Genealogists may find value in the documented Judith Cemetery and established ranching outposts like the Gibson Ranch Headquarters.
