Walk to Scott Base

On Sunday Jen and I walked over to Scott Base, the New Zealand base ~3 km away. Walking to that part of Ross Island you can see glacial pressure ridges at the edge of the ice shelf. Ice pressure ridges form when two ice sheet collided and ice cracks and rises upward. The collision could result from wind or tidal forces, movement of ice via ocean currents, or heating and cooling of the ice causing it to alternately shrink and expand. In this cause, it is thought that the pressure ridges form from tidal forces.
