Reported by: Park/Forest Service

A dry slab avalanche occurred on Tamarack Peak within the Hourglass Bowl at 0900PST 16 November and partially buried a female skier and totally buried a male skier. A quote from the Sierra Avalanche Center: The person who was still skiing when the avalanche hit her was blown out of her skis and they were buried. She may have hit a tree and her back began seizing up. The person buried had both skis but lost a pole and one skin and had a torn ligament in his ankle. Therefore from this report, it is evident that both the skiers were injured in this avalanche.
