SAR Staff, RAVEN, and the SVU responded to the dirt extension of Chimney Drive to search for an overdue elderly equestrian rider. A cell phone ping was successful part way into the search, but the location was somewhere in a line of about 5.5 miles. As SAR teams, RAVEN, and Tribal Police searched, a SAR ground team located the subject. The horse was in desperate need of water, although the rider refused water for himself. Family was brought into the area and assisted with walking the horse back to staging, while the lost subject was transported by side x side.
