The air and ground search for 19-year-old Jakson Kreiser, missing since he failed to return from a day hike last Saturday, continued yesterday. The park is using forward looking infrared technology (FLIR) technology in its efforts to find him. The cameras, provided by the Flathead County Sheriff’s Office, detect heat sources and are being used in early morning operations before rocks and vegetation warm up. Canine search teams from the US Border Patrol are also being utilized, as well as trackers from the North Valley Search and Rescue Team. The search is centered on the area between Hidden Lake and Avalanche Lake. Kreiser’s vehicle was located in the Logan Pass Visitor Center parking lot and it is believed that he was attempting a day hike from Logan Pass to Avalanche Lake. His intended route would include treacherous country filled with rock cliffs, waterfalls, wet and slippery rocks and boulders, and dense vegetation. The descent is more than 4,000 feet on steep slopes. Kreiser is a seasonal employee with Glacier Park, Inc. at Lake McDonald Lodge. A park incident management team has been organized and is managing the incident. Approximately 50 people are dedicated to the operation. Kreiser is from Michigan, and this is his first year working in the area. He is 6 feet 2 inches tall with black, short and curly hair and a black beard. It is believed that he is wearing a yellow sweatshirt and grey colored khaki pants is and carrying a grey and yellow backpack.
