As Winter sets in the temperature falls and the ground starts to freeze. It's not a complete freeze, more of a diurnal pattern of thawing and freezing a bit each day. And since parts freeze at different rates we end up with a lot of strange and fascinating ice formations. The ice comes squeezing out of the ground and plants as ribbons, columns, spikes and even "beards". Raz and I took a hike south of DHMC yesterday and these are a few photos from the walk.

Photos taken with iPhone 4S.

Some other collections: extruded ice, Haareis, diurnal freeze-thaw cycles.
