As he was filtering his morning water, Yosemite backpacker Chas Davis became aware of an adolescent-sized black bear that had hopped into Falls Creek apparently attempting to get to the other side.
Davis, standing with two other backpackers to give strength in numbers since there was another bear nearby, began videotaping the swimming bear from a bridge located near Vernon Lake about a 10-mile hike from the Hetch Hetchy trailhead.
