As the ice-cap moves down the slope and melts, there
are significant amounts of rock particles carried on the surface
that accumulate on the lowest slopes. Here you are
looking at ice covered in a layer of fine ground rock, the pyramid
and ridge-shaped structures are also made of this ground rock
and are around a meter high, why they should form liked this
puzzled me at least, there was no obvious reason though I'm
sure a glaciologist would be able to explain.
