"US Park Ranger McClure was patrolling on Yellowstone Lake by canoe. When he did not return to headquarters that evening or respond to radio calls, an extensive search began. Ranger McClure's canoe was located and determined that it had overturned in the extremely cold lake. Ranger McClure's body was never found so a Coroner's Inquest was held 06/09/1980. Ranger McClure was declared deceased on 06/09/1981."
