More pics from Pressure Ridges

Scott Base in background:

The sun is out 24-7 but freeze-thaw cycles caused by overcast days and lower temperatures brought in by weather fronts form these icicles. In a week or two melting and crack formation will make it unsafe to travel through the pressure ridge area.

Castle Rock in left background (an old cinder cone). Mt Erebus looms in right background with its top covered in cloud and vented gases.
