Boreas Pass is a high mountain pass at an elevation of 11,481ft above sea level, running through the Colorado Rocky Mountains at the crest of the Front Range. The road over the pass, formerly known as Breckenridge Pass, is now named Boreas Pass Road. This route was used by prospectors during the gold rush that were crossing from South Park in search of gold in the Blue valley around Breckenridge. At the summit is a mountain hut known as Ken's Cabin, built in the 1860's.
