Ice Rocks !

While driving around with our skidoos we came across a line of boulders today.

The Darwin glacier looked like a giant frozen river from the satellite. Similar to liquid water in rivers, glacier ice is flowing down the slope driven by its own weight. Where two glaciers converge they mark the beginning of a line of boulders laying on the surface.


We can track these features over time to estimate the velocity of the glacier. As the ice continues to flow towards the ocean, the boulders on the surface are buried in snow, out on the Ross Ice Shelf. If they reach the edge of the ice shelf they might be transported far away from Antarctica within an ice berg.

Bon Voyage!
