Four people died on the afternoon of Sunday, September 30th, when their aircraft crashed near Nonvianuk Lake. The pilot, a guide and two passengers from Royal Wolf Lodge were returning to the lodge from a fishing trip when the accident occurred. The pilot had contacted the lodge and advised them that he expected to be back at about 4 p.m. When the plane had not landed 45 minutes later, aircraft from the lodge were sent to search for it and the wreckage was found near the lodge. Lodge employees went by boat and hiked to the crash site and confirmed there were no survivors. The plane was a Helio Courier on floats. The bodies of the four crash victims remained at the site yesterday morning. Rangers and investigators from the National Transportation Safety Board were on scene. Official notification to the families of the victims was still pending at the time of the report. The cause of the crash is not known. Nonvianuk Lake is in the northern portion of the Katmai National Park and Preserve, about 50 miles northwest of King Salmon. The lodge is on private property within the preserve.
