The moose on Lake Superior's Isle Royale are some of the most closely studied animals in the world. Moose on the mainland of Minnesota are not so well known. There's more than 4,000 moose living in Minnesota's Arrowhead. Nobody's studied them at all. But a team of researchers is trying to change that. Mainstreet Radio's Stephanie Hemphill went along last week when the team was hunting moose to fit them with radio collars.
