About this map

Alma and the surrounding high-country mining districts are the focus of this 2022 survey, illustrating a landscape defined by historic hydraulic engineering and alpine terrain. The map traces several significant water-management features, including the Dyer Placer Ditch, Fairplay Mining Ditch, and Columbia Number 1 Ditch, which reflect the area's deep connection to industrial extraction. These man-made channels wind through the valley of the Middle Fork S Platte River, connecting prominent landmarks like Montgomery Reservoir and the Columbia Reservoir.

Genealogists and local historians can locate several burial grounds along the western slopes, including Buckskin Cem, Park City Cem, and Dudley Cem. The terrain rises sharply to the west towards the Mosquito Range, where high peaks like Mt Lincoln and Mt Bross loom over Red Amphitheatre and Buckskin Gulch. To the north, the crossing at Hoosier Pass and the Hoosier Pass Tunnel mark the critical transit point over the Continental Divide between Park and Summit counties.
