This is why I don't hike alone in the winter. About a half hour from my house, this is one my go to hikes. A fairly easy hike, but with a big section of rocks in the middle, and a whole lot of smooth rocks and always windy above the treeline.
Was about 40 degrees yesterday, but the ground was still frozen. Temps dropped to 20 overnight. The dude was lucky his phone worked and they got him quickly.
