How Search & Rescue Works in King County — And Where Your Support Makes an Impact
Search and Rescue (SAR) in King County is a coordinated network of independent volunteer organizations that respond under the authority of the King County Sheriff’s Office.
You may hear both the individual SAR units and the King County Search and Rescue Association (KCSARA) mentioned when a mission makes the news. While they may work together on missions they serve different roles within the system.
Understanding how the entire system works — including the role of local fire departments — can help you decide where to volunteer or direct your support.
Regardless of what team or teams are required for a rescue, the county dispatch center receives the 911 call and assembles the right parties.
How 911 Calls Become Rescue Responses
When someone calls 911 for a wilderness or trail emergency, the call is routed through the county dispatch center.
If the incident involves a medical issue, both the appropriate local fire department and the King County Sheriff’s SAR Deputy are notified.
Fire personnel and the Sheriff’s SAR Deputy work together to determine what resources are most appropriate for the situation.
Depending on the subject’s condition, terrain, and location:
- The fire department may handle the incident independently.
- SAR units may be deployed.
- Or both fire and SAR may respond together.
Fire departments are often able to respond more quickly, particularly when the subject is close to a trailhead or roadway. In these situations, fire crews frequently handle medical-only or short-distance evacuations.
When terrain becomes technical, access becomes difficult, or the subject is deep in the backcountry, SAR units are more likely to be deployed to provide specialized wilderness and technical rescue capabilities.
This collaborative decision-making ensures the right resources are sent — balancing speed, medical care, terrain expertise, and technical capability.
The Role of the SAR Units
The operational SAR units are independent 501(c)(3) nonprofit organizations that deploy into the field when requested by the King County Sheriff’s Office, based upon the need of each mission.
There are seven individual and unique all volunteer SAR units:
Mission: A team focused on providing transportation and logistical support in terrain that conventional vehicles can’t reach. 4×4 SAR aids other SAR units by transporting people, equipment, and supplies, supporting night road searches, traffic control, and radio relay operations.
Mission: Dedicated to saving lives through search and rescue activities in King County and Washington State, ESAR provides wilderness and technical ground search capabilities and offers continuous wilderness and leadership training for its youth and adult members.
Mission: Provides highly trained volunteer support in incident planning, logistics, documentation, communications, and administration for SAR missions and large events under the Incident Command System.
Mission: Specialists in mobile search and rescue using all-terrain vehicles, snowmobiles, or dual-sport motorcycles to access areas that even 4×4 vehicles cannot access. RSVU assists in remote searches, subject transport, and brings SAR teams and gear into hard-to-reach terrain.
Mission: To find and aid people in distress and assist law enforcement with evidence searches through specialized canine search disciplines, including air scent, trailing, and human remains detection.
Mission: A team of experienced alpinists dedicated to saving lives through search, rescue, and mountain safety education in steep, mountainous, and hazardous terrain throughout Washington. SMR specializes in supporting missions within technical backcountry terrain, searches any time of the year, so that everyone comes home from the backcountry.
Mission: A team of backcountry volunteer ski patrollers dedicated to helping people and saving lives by providing emergency medical/trauma care, avalanche safety and rescue, and wilderness mountain travel support year-round.
Each organization brings specialized skills and training to the field. Together, these units form a comprehensive volunteer response system serving King County.
And importantly, there is no cost to the person being rescued, made possible by community support and donors like you. By supporting Seattle Mountain Rescue, you’re not just funding rescue operations — you’re helping save lives and bring loved ones home.
