About this map

Bull Mountain dominates the western landscape of this Jefferson County quadrangle, where the steep, timbered slopes of the Deerlodge National Forest give way to the broad Boulder Valley. This transition zone is defined by a sophisticated 1990s irrigation network designed to manage the snowmelt from the high country. Man-made watercourses like the Murphy Ditch and Carey Ditch skirt the base of the mountains, tracing the contours to deliver water from the Boulder River and its tributaries to the valley floor.

Evidence of early high-country utilization appears in numerous named landmarks such as Quaintance Park, Wilson Park, and Long Park. The drainage patterns of Dunn Creek and Quinn Creek are deeply incised, creating dramatic features like Dunn Canyon. Genealogists and local historians may find interest in the isolated Cemetery located north of the ditches, and the various named water sources like Mc Kanna Spring and Quaintance Spring that supported local ranching and land use operations.
