Re: Coldest temperature you've ever camped in?

Back in the 80's climbing Mt Washington in N.H. in January. We hiked up the Lions Head Trail to the Alpine Gardens and it was like going from a normal cold winter day to narley artic conditions. Winds were steady 30-40 mph coming in from the W SW with gusts up to 60 or 70. Walking on windblown snowy - ice like surface with crampons was made difficult with shifting winds causing you at times to stumble forward and when you find youself along the edge of the Tuckerman Ravine, it was not aplace to be in these conditions. One time I had to crouch behind a large rock to get out of the wind so I could scrape the ice off the in side of my ski goggles.
Noticing a cloud cap above the summit we knew that conditions would steadly get worse if we were to continue.
We turned around and headed down to the base of Tuckermans to set up camp and try again for the summit tommorrow.
During the night temperatures dropped, I slepted in a North Face bag rated to -30 and was chilly. Woke up the next morning with frost 1/8" thick covering inside the tent, my contact lens was frozen in the lens solution (was kept in the inner pocket of sleeping bag).
A Forest Ranger had stopped by and questioned us if we knew the where abouts of a climber that had seperated from his partner the day before. After we informed him that we've seen no one, we decided to bail.
By the time we packed up and made it down to the trailhead in Pinkham Notch it was about noon.
We drove into North Conway and notice the Bank thermometer read -17 F at 1:PM., knowing this we can only surmize that the temperature the night before had to be in the -30's.
