Cole Murphy, 30, sustained critical injuries on Friday morning on Lincoln Mountain and passed away two days later.
A second patroller involved in the same incident also suffered serious injuries but is recovering after successful surgery.
Murphy's family released a statement highlighting his dedication to his work, his love for the mountain, and his partner, Hayley.
This marks the second death of a Mammoth Mountain ski patroller on Lincoln Mountain this year, following Claire Murphy's death in February during similar avalanche mitigation efforts.
