If you don’t live near the mountains, it can be a little bit freaky driving through mountainous areas prone to avalanches in a snowy winter. Avalanche warning signs warn you of the possibility of tidal waves of snow rushing toward highways, but what are you supposed to do about it if it happens? Drivers on I-70 briefly considered that question on Sunday, many probably in a bit of a panic as an avalanche boomed down a nearby slope into Tenmile Canyon and sent a snow cloud whooshing over the roadway. The driver in this car pulled over, presumably the right thing to do, watching as snow seemed to eat the road and the vehicles ahead. Nobody was hurt as the avalanche poured into a gully off the highway, but still. Jeez.
