Where are the Trolls?

I'm getting ready to go to Norway and Sweden so I'm thinking a lot about trolls.  One of my favorite Stephanie Hemphill (MPR reporter in Duluth) stories is her interview with Lise Lunge-Larsen, Duluth storyteller.  Lise, a native Norwegian living in Duluth, tells many stories about such creatures.  She also writes books about them.  Stephanie's interview took place in the summer time (should I be thinking about summer as at this moment I am cleaning up the gardens, hunkering down and buttoning up my house and jacket?) in Lise's garden where she was talking about her then latest book, The Hidden Folk: Stories of Fairies, Dwarves, Selkies, and Other Secret Beings.  My other favorite book of hers is strictly about trolls: The Troll With No Heart in His Body.

Armed with Lise's stories, the folk tales Asbjørnsen and Moe collected in the 19^th century and paintings by the Swedish artist John Bauer I'm off in a couple weeks to make my own acquaintance with a troll or two.

You can listen to Stephanie's interview with Lise Lunge-Larsen on Stephanie's MPR web site.

Living near to Lake Superior, I've often wondered about what kind of secret beings live in or near here.  What stories do Native Americans tell about the beings that inhabit this area?  If you know, please share.
