While this “snow roller” looks like a whimsical sculpture straight out of Whoville (or a giant frosted donut), this meteorological phenomenon actually signals a heightened risk of avalanche. Often in the shape of a disk or ball, they form when the surface grows wet + the bond holding the snow together weakens.
With the holidays fast approaching, many Portlanders will be heading to the mountains to ski + snowboard, so it’s important to know how to enjoy the slopes safely. It may be tempting to stop and take a few photos, but it’s best to just keep moving.
