A search for Kreiser began July 29 after he was reported missing when he failed to return following a hike on July 28. Glacier National Park employees, with assistance from North Valley Search and Rescue, Flathead Search and Rescue, Can Am Search and Rescue, Flathead County Sheriff’s Office, Lake County Sheriff’s Office, and the US Border Patrol, conducted an extensive ground and aerial search for eight days before scaling back efforts.
The search area was focused between Hidden Lake and Avalanche Lake, and in the Floral Park area. This area includes some treacherous country filled with rock cliffs, water falls, wet and slippery rocks and boulders, and dense vegetation.
Kreiser, age 19, was from Michigan and a seasonal employee with Glacier Park, Inc. at Lake McDonald Lodge. This was his first year working in the area.
