About this map

The silver-mining settlement of Alta sits at the high-altitude junction of Little Cottonwood Canyon and Collins Gulch, serving as a central hub for an expansive network of subterranean operations in the mid-1950s. This survey records a landscape defined by intensive extraction, where tunnels like the Emma Tunnel and Wasatch Drain Tunnel pierce the ridges of the Wasatch National Forest. The map documents numerous historically significant claims, including the Cardiff Mine, Flagstaff Mine, and South Hecla Mine, alongside legacy sites such as the Quincy Mines.

Beyond the industrial activity, the terrain is marked by high alpine hydrology, featuring clusters of lakes like Lake Blanche, Lake Lillian, and Lake Florence below Dromedary Peak. To the west, the Power Plant and Quarry near Little Cottonwood Creek illustrate the downstream infrastructure supporting the region. The map also delineates the boundary between Salt Lake Co and Utah Co, showing how these steep drainages transition from mining districts into the protected lands of the Big Cottonwood State Game Preserve.
