A route done by Bill Briggs in 2000 and possibly never repeated? Starting at Cataract Lake trailhead and finishing at Brush Creek trailhead, Briggs ascended Peak A through Peak O in the Gore Range. He cut a corner and skipped Peaks I and J. This is a seldom visited and obscure area, so it can be hard to find out anything about these summit. A rough idea can be found at the map here: http://www.peakbagger.com/peak.aspx?pid=37294 Briggs estimated 25 miles with 11,000' of elevation gain, and much tricky scrambling. The traverse includes Eagles Nest Peak (Peak A), Mount Powell (Peak B), Gore Thumb and 3 summits of Guyselman Mountain (Peaks M, N and O)
