Mining operations and high mountain terrain define this 1958 survey along the Continental Divide. The settlement of Empire sits at the junction of Clear Creek and Mad Creek, serving as a vital corridor through the Front Range. The landscape is heavily marked by its mineral history, particularly around Alice, where the Glory Hole and the Ninetyfour mine are found. To the south, the Bellevue-Hudson Tunnel and the Minnesota Mines overlook the valley floor, while further north, the high peaks of James Peak and Mt Bancroft tower over glacial features like Loch Lomond and St Marys Glacier. This era shows the local infrastructure supporting both extraction and early recreation, with St Marys Lodge and various pack trails and the Ute Trail threading through Arapaho National Forest and Roosevelt National Forest.
