I just returned from an overnight on top of Glastenbury Mountain (elev. 3750'), Vermont. The rain stopped during the late afternoon, but high winds continued throughout most of the night. With clear skies, the temperature dipped into the mid 20's. Had the WBBB, 3 season Yeti, Nunatak Specialist, and OES custom Spinn. With a bit of help from Icebreaker underwear and a Montbell UL inner parka I stayed warm enough throughout the night. No photos this trip since I somehow left my Blackberry on and had a dead battery.
