Upper Blue Basin Overview

This Basin begins near the southern shores of Lake Dillon, in the Farmers Korner area, and extends southward through the towns of Breckenridge and Blue River to the summit of Hoosier Pass. The easternmost portions of the Basin extend to the crest of the Continental Divide and the westernmost portions reach the crest of the Tenmile Range. Approximately 78 percent of this Basin is National Forest System land, the majority of which comprises undeveloped mountainsides. The primary areas of development are within and adjacent to the towns of Blue River and Breckenridge, in close proximity to the valley floor of the Blue River. The Basin is home to the Breckenridge Ski Area, one of the nation’s most popular ski destinations. Elevations in the Basin range from 9,014 feet at Lake Dillon to 14,265 feet at the summit of Quandary Peak.
