1986 Map of Dunn Creek

About this map

Deerlodge National Forest and the peaks of Bull Mountain dominate this mid-1980s landscape in Jefferson County. The map details a rugged transition between high timbered ridges and the irrigated lowlands of the Boulder Valley. Water management is central to the local geography, evidenced by the Murphy Ditch and Carey Ditch which draw from the Boulder River to support ranching in an otherwise arid climate. Genealogists and local historians will find several family-named landmarks and essential water sources, including Mc Kanna Spring, Quaintance Spring, and Mulvey Creek. The presence of a Cem near the northern boundary and established routes like Brady Gulch and Jack Gulch reflect the enduring footprint of early homesteading and resource extraction in this part of Montana.
