Claire Murphy was conducting "avalanche mitigation" work on Valentine's Day when she and a colleague were caught in an avalanche. Ski resort officials announced her death Saturday.

A Mammoth Mountain ski patroller who was injured in an avalanche last week has died, according to the resort. On Saturday, Mammoth Mountain Resort said ski patroller Claire Murphy died Friday night after she was caught in an avalanche on Feb.

Murphy was doing avalanche mitigation with a team of ski patrollers on Lincoln Mountain — a dome peak within the Mammoth Mountain ski area — when an avalanche broke loose in an area known as the Avalanche (Avy) Chutes on Friday, Feb. 14. The accident occurred after approximately six feet of snow fell in 36 hours following a heavy Sierra snowstorm.
