2020 Map of Mission

About this map

The confluence of the Shields River and the Yellowstone River anchors this Park County landscape, where water management has long dictated the layout of the land. A complex system of irrigation, including the Middle-Windsor Ditch, Upper Windsor Ditch, and Vallis Ditch, illustrates the agricultural engineering required to sustain the valley. The small settlement of Mission sits near Mission Field, surrounded by a network of ranch roads and historic paths like the Horse Thief Trl. Genealogy researchers will find several notable landmarks, such as the Poor Farm Cem and Bruffey Cem, reflecting the early community's history. The terrain transitions from river bottoms to higher elevations marked by Poison Cr and Mission Cr, with travel routes like Convict Grade Rd and Old Boulder Rd following the natural contours of the Montana countryside.
