Near Lassen Peak National Park, California, off a cross-country ski trail. The outer layer of snow on the slope has peeled back under gravity to wrap around into a roll. These are pretty common in mountain country. They require a slope and an uppermost layer of snow that isn't well bonded to those below. Those are, of course, the same conditions that lead to avalanches!
