Excellent capture Jim, nice details in the shadows and highlights. Was thinking of possibly heading out on Thursday, but by then (if not already) the snow on the ground will probably have all melted. Of course, doesn't matter if you can catch him in the air like this!
I live in Surrey, British Columbia just north of Bellingham Washington and we see these often. In fact last year was a banner year for the snowies. Your photos of this wonderful Raptor are very awesome. Detail is striking..
