Pressure Ridges



SOUTH POLE STATION, ANTARCTICA– Before I left McMurdo, I got a tour of the pressure ridges near Scott Base (the New Zealand station very close to McMurdo). The pressure ridges are formed by tidal forces — there is a thick sheet of sea ice which meets the land, and tidal forces cause the ice to buckle. Members of the New Zealand base use flags to map out a safe route, and we were allowed to walk around these marvelous ice formations one evening. Our guide was Peggy Malloy. The trip was a lot of fun!

  1. Beautiful pictures, thank you, my grandsons Chris and Brenden would like to go to Antartica, perhaps some day when they grow up. Have a Happy Summer!
