SAR Staff, Hasty BC, SVU Tracked Vehicles, and WCSAR BC began responding to Sheeps Flat to locate a cross-country skier that became separated from a group during a snowstorm. The subject did not have a phone with her, so location retrieval was not possible. As teams were beginning to go en route, the subject was located by an WCSO Incline Village Deputy along the highway on the Tahoe side of SR431.
