North
Maroon
Peak

Percy Hagerman and Harold Clark made the first recorded ascent on August 25, 1908; Hagerman first climbed neighboring Maroon Peak the same summer. Separated from its taller neighbor by only about 0.3 miles, North Maroon nonetheless demands harder climbing: the standard Northeast Ridge route is a Class 4 scramble past loose, downsloping mudstone, and the Bell Cord Couloir splitting the two summits is a well-known, steep spring ski and snowboard line.

For decades North Maroon was treated as an unranked fourteener, its saddle with Maroon Peak measured at 13,780 feet — short of the 300-foot rise Colorado's ranking convention requires. In late 2021, peakbaggers Adam Klopp and Ben Loftin independently found that the USGS maps omitted several contour lines near the saddle, correcting its elevation to 13,693 feet and raising North Maroon's prominence from 234 feet to 329 feet, formally qualifying it as a ranked peak.
