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.

Claire Murphy and another ski patroller were injured on February 14 after being caught in an avalanche on Lincoln Mountain.

Two ski patrollers were caught in an avalanche Friday after heavy snowfall from a recent atmospheric river triggered a slide on Lincoln Mountain in California’s Sierra Nevada.

Murphy was one of two ski patrollers swept away by an avalanche on Lincoln Mountain in the resort while doing avalanche mitigation following a heavy snowstorm, the resort said. It was closed to the public at the time. The second patroller was uninjured by the 11:30 a.m. avalanche, the resort said. Murphy was hospitalized with serious injuries.

A Mammoth Mountain ski patrol employee has died after sustaining serious injuries last week from an avalanche.
