Pressure Ridges

These pictures are from a tour I did of the pressure ridges.  Pressure ridges are formed when the permanent ice shelf meets up with the sea ice.  The differences is that sea ice will sometimes completely melt then later reform.  The current sea ice has been around for several years.  The two will meet then start to push up ice/snow like sculptures.  They were amazing to see and walk through.  Hopefully you can really see them in the pictures.  It was also cool because all of them had this blue glow to them from the water and ice.  In some of the pictures you can see the rich blue/green color of the water.

This first picture is my first steps on the sea ice (Where I landed when I arrived at McMurdo was on the ice shelf).

This obviously is my favorite picture.  I took about a hundred of them holding the axe with different poses.  Directly behind me looked like a rip curl from a wave.

Violet, this is the closest thing I could find to an igloo.  Violet wanted a picture of an igloo while I was down here.
