Twenty-seven-year-old Jacob "Jake" Rigby works as a seasonal employee at Glacier National Park in Montana.

Park officials say Rigby went on a personal hike in the park on Sunday and has not been seen since.

Authorities found Rigby's car at the southern end of the park and believe he signed the registry at a nearby hiking trail. Officials say that area of the park is extremely steep and treacherous.
