Something odd was bubbling beneath the surface of northwest Montana's Flathead Lake this summer. It wasn't lake monsters, but submarines. The subs' pilots were there to help cash-strapped researchers explore the depths of Flathead Lake for free.

It can be hard for research divers to see what's at the bottom of deep bodies of water like Flathead Lake without special equipment and experience. So, having a couple of submarines around this summer was helpful to the University of Montana's Flathead Lake Biological Research Station.
