This morning, it was 34F (1C) at 6 a.m. The wind shifted 180 degrees during the night and was blowing up the slope where he was hanging and right into his hammock. He got up and rejigged the tarp but was limited in how he could fix it. The insulation he was wearing for the night got damp (I guess from the wind?) and he was not sure if it would dry out as he started walking.
As he lay there, too cold to get up, he contemplated packing quickly and heading up the trail to cook breakfast and dry out in sun. He wasn't sure if there would be a sunny space where the other tenters were, where he could cook and dry out. They were all about 60 yards away from where he spent the night.
After he got up, he checked and his weather App said the winds were at 35 mph, which he knew was true based on his hammock being buffeted by winds, making if difficult to peck out letters on his iPhone keyboard! He figures there was a wind chill below freezing this morning.
That blue blaze on the tree in the photo means the water was on a side trail. The main Appalachian Trail is marked in white blazes.
