About this map

The Helena National Forest dominates the southern landscape of this 1985 survey, marking a transition from the agricultural and settlement patterns of the Helena Valley into the timbered slopes of the mountains. Small settlements like Louisville and Clasoil sit along the central corridor, positioned near the junction of several county boundaries where Lewis and Clark, Jefferson, and Broadwater counties meet. These modest communities were established in an area defined by its water resources and utility infrastructure, with a prominent Canal, Pipeline, and Transmission Line cutting across the terrain.

Industrial activity is evidenced by scattered Prospects in the hills near Mitchell Gulch, suggesting a history of mineral exploration. To the east, the Spokane Hills rise above the drainage of Spokane Creek, while the southern reaches near Little Butte and Deep Gulch show the complex topography of the national forest boundary. The map captures a moment of modern utility expansion layered over traditional mountain resource extraction and small-scale valley settlement.
