What in the world is this?

I like to explore the planet using Google Earth.  I use it before trips (the anticipation stage, see Clawson and Knetsch 1966).   And I use in the recollection stage as well.

When I fly I also like the window seat to watch the land beneath.

So anyway, I was playing around with Google Earth retracing a flight from Europe where we flew over Eastern Quebec and Newfoundland and Labrador and discovered this.

What the heck in the red stuff?  See it for yourself.  Well it is the waste from a mine.
