Pressure Ridges

The sea ice outside Scott Base forms large pressure ridges as it’s forced against the land. These make for a very interesting icy landscape. McMurdo residents are only allowed there on guided tours. Luckily for us, Anne from LDB is qualified to give these tours. She was kind enough to take us out, at 4am a couple days ago.

It was very cold, which makes for poor photography and intermittently frozen lenses (and excuses, apparently). The weather was Condition 3 ("good"), otherwise we wouldn’t be allowed out. Still, it’s nice when Antarctica occasionally demonstrates its extreme environment, rather than being a sunny (if slightly cold) summer paradise.
