USOs: Unidentified stationary objects

I'm guessing it is either a peat farm or a cranberry farm.  The colors are bewilderiung though to say the least...

It's got to be peat mining. I know there are operations up that way, and the color in the aerial view is similar to the color in the ground-level photos with this article:

Anyone have a direct google maps url to look at? I'm curious, but my work blocks MPR & Facebook links. :(

On a similar note, I have been baffled by this oddity on the range just off of 169 for years.  I have always assumed it has something to do with all the mining in the area...

I think those are giant holes to the center of the earth.. much more cool then my peat bogs.

Nashwauk should be careful, those holes are almost as big as their whole town, they could slip in and be gone forever.

I wanna say that the stuff by Nashwauk is the water treatment place.... or it could be the magical place where our power comes from that we're going to be selling to the mine that *might* open when hell freezes over.

Then again, I have no flippin' idea. It's hidden behind some tower mine dump mountains. I've seen city trucks go back there quite a bit, but the road isn't paved (I don't believe). I could ask my redneck neighbors who have them there 4-wheelers that they ride around back there, but they scare me and I value my life. :D
