Flash-Frozen - Greenough Park, Missoula, Montana

Massive slabs of ice stacked willy-nilly block our usual winter walking trail, far up from the edge of Rattlesnake Creek. A sudden temperature change in mid-December created just the right conditions for dramatic flash-freezing, followed by a large-scale shattering and surge downstream, which changed the winter landscape overnight. And, of course, we can be thankful for weeks of bitter below-freezing temperatures for preserving this phenomenon for our continued enjoyment.
