SAR Staff, Hasty Team BC, RAVEN, and WCSAR BC responded to the Michael Thompson Trailhead to locate a hiker with a possible broken ankle. Some rain showers had come through the area, making the trail more treacherous than normal. The lead ground teams were able to access the location just as RAVEN arrived in the area. A hoist was performed and the subject was transferred to a REMSA ambulance at a landing zone near the staging location. On the way down, the lead team encountered another group of hikers that were out of water and were traveling extremely slow. Water was supplied to them and they were very slowly escorted down to staging.
