Road Ripples
On the morning after the infamous Christmas Eve blizzard, interesting snow effects abounded in many places, including sastrugi: dune-like, wind-formed ripples in snow. This example developed from windblown snow originating off-road, but only after the street had been stripped down to the icy underlying layer that itself had formed from compaction and melting of earlier snow. It all made for a fascinating array of frigid formations seldom found in central Oklahoma.
