2024 Map of Louisville

About this map

Helena Valley Southeast provides a transition between the northern valley plains and the rising peaks of the Elkhorn Mountains. This landscape is defined by the headwaters of numerous drainages, including Spokane Creek and Deep Creek, which carve through the terrain as it climbs toward the Helena National Forest. Small settlements like Louisville and Clasoil sit along the central transport corridor, while Montana City marks the southwestern extent of the mapped area. For genealogists and local historians, the inclusion of the Turner Cem near Mitchell Gulch offers a specific point of interest for family research. The map also captures the complex intersection of three counties—Lewis and Clark, Jefferson, and Broadwater—illustrating how political boundaries follow the natural topography of the Montana highlands.
