Twilight on the largest freshwater lake in the contiguous western United States casts a bigger shadow starting in June 2009. Sail into the sunset on the new tour boat operated by Kwataqnuk Resort and the Confederated Salish and Kootenai Tribes on Flathead Lake.

The four-year-old craft, imported from northern Idaho in June, provides seating for 150. It replaces the Princess with three times the passenger capacity.

The Shadow will run three daily summer tours: A morning jaunt around Polson Bay, a three-hour afternoon cruise to Wild Horse Island, and a twilight trip.
