After the previous weekend we were intent on finding a north facing couloir to climb - we found one on the north side of Flattop Mountain in Rocky Mountain National Park. According to Gillett, Flattop Gully saw its first ascent by Topher Donahue only 7 years ago in 1999. It surprised me that such a fun route on such a popular mountain had seen so few ascents - add us to the list!
