The Altadena Mountain Rescue Team is staffed by reserve Los Angeles County Sheriff deputies (all volunteer).
The team conducts weekend patrols of the mountain areas within its jurisdiction, namely the 20 canyons behind Altadena and Pasadena.
These patrols ensure a quick response to emergencies during a time when they are most likely to occur, and serve as a means of fire prevention and mountain safety.
The professional occupations of volunteer members have included: teachers, paramedics, construction contractors, lawyers, registered nurses, chiropractors, mechanical and electronic engineers, physician assistants, police officers, firemen, and corporate managers.
As a nonprofit corporation, the Altadena Mountain Rescue Team is governed by a five-member Board of Directors.
