Multnomah County Sheriff's Office Search and Rescue
Multnomah County Sheriff's Office Search and Rescue (MCSO SAR) is a non-profit volunteer search and rescue resource for the Multnomah County Sheriffs Office in Multnomah County, Oregon, United States. The agency also offers its 3,000-5,000 hours of volunteer service to other areas, including Clackamas, Columbia, Washington, Marion, Hood River, Wasco, Tillamook, and Clatsop counties in Oregon, and Skamania and Clark counties in Washington.
