Frost Quakes

The weather here over the last week has been atrocious. First a heavy snow fall, followed by a thaw, freezing rain, then the temperature plummeted to -24oC. Yesterday, everything was frozen solid, then today, we're having another couple of feet of beautiful powder, which is great for the skiers amongst us, but loathsome to the drivers.

One thing to come out of this, was my learning of this wonderfully strange phenomenon, frost quakes, or cryoseisms, or as I now rename it, Ithaqua's footprints. Or maybe even ice shoggoths on the move.

Ice shoggoths, now there's an idea...
