About this map

The Helena street grid terminates abruptly at the foot of Mount Helena, where the landscape shifts into the protected heights of Mount Helena City Park and the Helena National Forest. To the west, the Fort William H Harrison Military Reservation occupies a significant portion of the foothills, while the city's northern outskirts transition into the Green Meadow Game Preserve.

A network of drainages defines the southern terrain, where Last Chance Gl and Grizzly Gulch lead toward the historic mining sites around Unionville and Park City. Numerous named Mines and Prospects are scattered across these gulches, reflecting the region's enduring extraction history. The infrastructure of the Helena Valley Canal and Sewage Disposal facilities in the north provides insight into the mid-80s development and water management of the capital city.
