Ice cave opened up in collapsed snow-slope
Base H - Signy Island Antarctica

  ©Copyright D. Allsop - picture taken 1980 / 1981

Melt water flows down under the snow slope making a cave. Eventually the cave gets too big and the roof can't support itself so it collapses. There's snow algae giving a pink tinge to the sides of the slope too. This is algae that grows inside the ice fed by the minerals in the melt water that run over the snow and ice and in response to longer daylight hours in the spring and summer months.

Apparently this algae smells like melon when you walk on the snow, though I can't say I ever noticed it, of course now I know, I'd be readily placing my nose a few cm above the snow surface to check it out.

This picture is one of a collection assembled in 2007 on the 60th anniversary of Signy Island Base: 60°43'S 045°36'W. Thank you to those who sent their treasured memories of their time in Antarctica and allowed them to be made into a commemorative cd and then placed here on the web.

The reunion weekend was 14-16 September 2007.
