Portnuef River WInter, oil on canvas, 24 x 48, oil on canvas. I drove from the Idaho cabin all the way to Charleston, SC to my winter digs last year. I left Idaho the day after Halloween, and drove into the first snow of the season. The Portnuef River has hot spring water pouring into it in a few places, and the water has a purple hue in the right light, and the red branches really pop with the snow and purple water. This was between Sun Valley and Lava Hot Springs Idaho.
