The ice foot is a shelf of ice
attached to the land that forms when the tides rise and fall in very
low temperatures. A thin layer of water is left behind which
ends up smoothing the transition between land and sea. The large
slabs of ice in the bottom right of the picture were attached to the
land, but are now breaking away, but are currently held in place by
rocks that come near to the surface.
When the sea-ice breaks out coasts
have a shelf all around them which can give a nice smooth walking
surface, snow permitting of course. The only problem is that you
have to follow the line of the coast to get anywhere - or go
the more direct but more rugged route.
