Quite a few years back, I crossed the High Sierra mountains mid winter with snowboarding legends Tom Burt and Jim Zellers. National Geographic Photographer Bill Hatcher documented our seven-day Sierra Crossing. Here is a photo from that trip. I am preparing to traverse a slope behind Jim, who is up in the distance. It was storming, and the trees bent to one side indicated the avalanches that had ripped through this area in the past. What a trip! Take a look at Bill’s photography on this site.
