About this map

Mackay serves as a focal point of settlement in the Big Lost River Valley, where the town’s grid is anchored by streets like Main St and Elm Ave. To the north, the terrain climbs sharply into the Lost River Range and the Challis National Forest, dominated by the massive peak of Mt McCaleb. This landscape reflects a sophisticated system of high-desert water management, as evidenced by a complex network of irrigation channels including Nielsen Ditch, Sharp Ditch, and Burnett Ditch that feed the agricultural valley floor.

Evidence of local history and infrastructure is clear at Houston and the Mount McCaleb Cem north of the town center. The geographic transition from the high peaks of Invisible Mtn to the depths of Rio Grande Canyon highlights the varied topography. In addition to the natural features, the Mackay Airport and names like Smelter Ave point to the area’s long-standing role as a transportation and industrial hub for the surrounding mountains.
