In the middle of a chilly October night in 2025, my two friends and I suited up at the Cottonwood Creek trailhead and started a trek into the Sangre de Cristo mountains of Colorado. It was a little below freezing as we got moving at 1:30 a.m., and the Moon illuminated the snowy mountaintops above us.
Our packs were a bit heavier than normal because we were hauling highly accurate surveying equipment to the summits of two peaks, each over 14,000 feet (4,267.2 meters). The peaks, Crestone and East Crestone, were close enough in height, with a short enough saddle in between, that only the taller of the two would count as a true 14er and the other as a sub-peak.
