SAR Staff, Hasty BC, RAVEN, SVU, and WCSAR BC began responding to the Whites Creek Trailhead area to search for a subject that fired of his PLB. RAVEN was first in the area but was not finding any evidence of a hiker being in the area of the coordinates. The subject’s vehicle was located at one of the Galena Park lots. As teams were arriving at staging, the subject walked out to his vehicle. He had fired off his PLB due to a medical episode but felt better after a short period of time. He was checked by a Hasty medic and released.
