Mount Marcy is the final peak stop on our proposed four-summit day, but it doesn't have to end there. We hiked the ridge from Gibbs to Marcy and then returned to our camp in the upper part of South Brush Creek. But there are several other ways these peaks can be completed and several other peaks could be included such as Cotton King, Silver and Spread Eagle. See our separate write-ups for them. As for the Gibbs to Marcy hike, the 1.5 mile traverse is no more than Class 2 with one rockier section around Pt. 13,335. Use Gibbs Peak as the "access" for Marcy in this description. For trailhead access, on the east side of the range, use either the Ducket Creek TH or the Gibson Creek TH, both of which will utilize the Rainbow Trail to reach South Brush Creek. From the west side of the range, use the Cotton Creek TH. Lidar measurements have added 14 feet to this summit.
