LATEST UPDATE: Fish, Wildlife and Parks officials tell NBC Montana they are investigating a bear attack in the Centennial Mountains, east of Dillon. A bear specialist, local wardens, the U.S. Forest Service and U.S. Fish and Wildlife are currently on the scene.
FWP officials say the group is looking for evidence of the attack, such as hair, tracks, blood, clothing, or the bear itself.
According to FWP officials, a father and son were hunting black bear in the Centennial Mountains. Around 11 a.m. Sunday, the father found his 47-year-old son had been mauled by a bear.
The father took the son out of the area to meet a Lima ambulance. The hunter was first taken to a hospital in Dillon, then transported to a hospital in Seattle to be treated for serious injuries.
FWP officials say they had a brief interview with the father and the Dillon hospital. The father is in Seattle with his son.
Officials don't know what species of bear attacked the hunter, nor how many bears there were.
