There is a lake next to my neighborhood and it has Middle-earthian qualities in the park. My little brother walked around it with backpacks and walking sticks barefooted last summer, we go some strange looks, we also quoted half of FotR...
Some of it looks like the Old Forest, other parts of it look rather like Lorien and some of it is very Shire-like. Plus it has one of the colleges in Anchorage right next to it, so it is kind of Long Lakeish, and the Chugach mountains in the distance, which sometimes can look very much like the Misty Mountains in the winter when there is snow.
Alaska can be very Middle-earthish sometimes...
