Boreas Pass

For centuries, numerous passes over the Continental Divide allowed people to enter or leave what is now Summit County:  Ute Pass in the Williams Fork Range, Loveland Pass, Argentine Pass -formerly known as Sanderson’s Pass and Snake River Pass, Grizzley Pass, Webster Pass – formerly known as Hand Cart Pass, Georgia Pass – formerly called Swan River Pass, French Pass, Hoosier Pass – formerly called Ute Pass, Fremont Pass, Shrine Pass, Vail Pass—–and Breckenridge Pass.  Breckenridge Pass?  Where was Breckenridge Pass?  Was it originally Hamilton Pass as some have said?  Or is it a separate pass with an unknown location?  Could it be the original name of Boreas Pass?
