Accident and Rescue Summary
A close call occurred this afternoon when two riders were caught and carried by a scary avalanche just north of the Idaho State Line in the Bear River Range. The party of four was riding a bit northeast Corral Hollow, near the ridge between Franklin Basin and Egan Basin. The avalanche happened on a northeast facing slope at around 9000' in elevation, while two of the riders were dealing with a stuck sled about 60 feet below the main ridge. The third rider had turned out of the gully below the two, and was below and well out of the way when the forth rider triggered the avalanche from the ridge. The avalanche involving wind drifted snow only ran about 100 feet, but it swept up the two riders and sleds in it's path. One deployed his airbag and ended up on top of the debris. The other was partially buried with only one leg sticking out of the snow. Luckily, neither rider was injured.
Both riders are quite okay, and they were able to ride their sleds out of the backcountry this afternoon.
Comments
This from the rider who was partially buried,
"Looked like wind slab. My column tests just to the north were failing at the old snow on 2 from shoulder. This broke half that depth and damn lucky of it!"
