Expanding his dominance of the Colorado 14ers, Andrew Hamilton became the first person to complete all 58 peaks in one calendar winter. The previous year, Will Seeber had completed 51 peaks, the most to that time. Hamilton's quest was followed enthusiastically on a thread on 14ers.com. In the thread, Hamilton himself gives detailed reports of many harrowing (and really long!) outings that were required to complete the project, including a 53-hour traverse of Capitol, Snowmass and the Maroon Peaks, and the first winter crossing of the Nolan's route. Note that Hamilton's time is from the first trailhead (Purgatory) to the last (Quandary), vs. the standard summer 3000 foot rule.
"Before this year I hadn't actually climbed any peaks in winter, although I have lots of experience in spring with the late snowpack in recent years. Despite the relative lack of snow this year, I'm discovering that the cold temperatures and wind really take the suffering to the next level in winter..." - Andrew Hamilton, 1/15/2018
