On August 11th, the park received a request from the Flathead County Sheriff's Office for assistance in stopping a vehicle involved in a high speed pursuit on U.S. Highway 2 that was headed toward the park. The suspect vehicle was reported to be traveling at speeds in excess of 100 mph and against traffic. Rangers Gary Moses and Ron Goldhirsch immediately set up a roadblock in the eastbound lane of Highway 2 just west of the junction with the Going to the Sun Road, utilizing parked patrol vehicles to constrict the road width. The driver, subsequently identified as Joshua Hansen, an escaped convict from Nebraska, attempted to breech the roadblock and in the process struck Moses' vehicle at a high rate of speed. After striking the patrol vehicle, Hansen lost control of his car, which skidded across the oncoming traffic lane, flipped, and came to rest just west of the railroad bypass tunnel leading into the community of West Glacier. Hansen fled on foot into that community. Rangers immediately established containment of park access routes and pursued Hansen on foot, following him into a densely wooded area by the Middle Fork of the Flathead River, directly across the river from the park housing area. Ranger Stephen Willis found Hansen hiding in the dense brush and placed him in custody without further incident. The vehicle that Hansen was driving was reportedly stolen in Columbia Falls, Montana, earlier that day. The Montana Highway Patrol estimates that Hansen was traveling in excess of 96 mph when his car hit the ranger vehicle.
