I think I had no idea that I would be living in a mountaineering tent during the time I was out in the field. (A mountaineering tent is a dome-shaped nylon tent with a rain fly.) People are shocked---"Wasn't it cold?" everyone asks--"you actually slept in a tent...wow!" In fact it wasn't that cold--a warm sleeping bag, 24 hours of sun (or just light on a cloudy day) and the fact that one does adjust makes tent sleeping very comfortable. I had a few chilly nights ---I used a hot water bottle once and the other times I did warm up nestled in my sleeping bag. As a matter of fact the dormitory room at McMurdo felt hot and stuffy after fresh air sleeping. I thoroughly enjoyed my tents at Lake Hoare, Cape Royds and the Scott tent at Cape Crozier. (Scott tents are larger and heavier--square bottomed and pyramid shaped--used by Scott 100 years ago when exploring Antarctica. They are less warm than the mountaineering tents--but you can stand up in them so they are better for clostrophic types.)
What was the temperature in Antarctica?--the question asked the most after, "Did you see penguins?" Most of the time the temperature on Ross Island (Cape Royds, Crozier and McMurdo Station) and Lake Hoare in the Dry Valleys-across the frozen Ross Sea was hovering around freezing and dropping to the high teens. (I know--NY was colder.) The South Pole was minus 26--I was told I was there during a heat wave. Now it is minus 72. It is 13 degrees F. today but dropping down to minus 7 later this week at McMurdo. The wind was brutal at times--my fingers froze one very windy day when I was walking from one side of McMurdo Station (which is really like a small town) to the other.

I was given a full tour of the three telescopes at the South Pole by their respective scientists. The South Pole telescope was immediately noticeable by its extraordinary form. You can find out more about this telescope at http://pole.uchicago.edu/blog/2008_10_01_archive.html. I found all telescopes at the South Pole so sophisticated that I know if I begin to describe their function I will get it wrong--they all sound like science fiction to me--for that reason I will refer to websites.
Housed in the same building is BICEP. This is the acronym for Background Imaging of Cosmic Extragalactic Polarization, and again I will refer to a link because I can't begin to explain this telescope although it was graciously and generously explained to me. http://www.polartrec.com/node/11229
I did not see much of the neutrino telescope Ice Cube as much of their visible work was finished for the season. They have a very extensive website with detailed explanations at http://www.icecube.wisc.edu/info.

I also visited the clean air facility (AR0) and the underground tunnels that carry water and fuel and are about minus 60 degrees at all times.
And speaking of minus 60 --that seems to be the temperature there right now!
And the magnetic Pole--with Gumby in his Big Red....
