Gardner was swept away by rising water while hiking on May 12th. His body was found downstream in a rough area of the river with boulders the size of vehicles and buildings, according to the Lieutenant Kathy Curtice of the Fresno County Sheriff's Office.
Lieutenant Curtice said of the gorge, "It's almost got a lot of different areas that are kind of cavernous and very dark and in areas the water disappears beneath the rocks."
Crews used a drone, airplanes, boats, search dogs and a helicopter to try to find him, but it took searchers physically getting into the water to maneuver in and around the rocks.
