2011 Map of Frisco

About this map

Frisco serves as the central hub of this Summit County landscape, where the waters of Dillon Reservoir meet the steep slopes of Royal Mountain and the Tenmile Range. The map reveals a complex history of resource extraction and infrastructure, notably featuring the Harold D Roberts Tunnel and various mining sites such as the King Solomon Mine and Frisco Mine. The geography is defined by the massive reservoir, including its distinct reaches like the Snake River Arm and Blue River Arm, which submerged parts of the old valley floor. Traces of earlier settlements and land use remain visible through labels for Masontown, Braddock Flats, and Delaware Flats. Beyond the water, the terrain is marked by high-altitude features like Ophir Mountain and Peak Seven West, while local transportation and utility are represented by the Breckenridge Airport and the Old Dillon Dam near the smaller Old Dillon Reservoir.
