The Flathead Lake Monster
Montana's lake monster was supposedly first reported in 1889, when steamboat captain James C. Kerr said he and about 100 passengers saw a huge whale-like animal in Flathead Lake.

The account
Indigenous stories of a creature in the lake predate settlers. Sightings continue at one or two a year; there were about thirteen in 1993 alone.
The sceptical view
Large white sturgeon (one of 181 pounds was caught in the lake), wakes and floating logs explain many reports.
