Brown Air Over St. Paul

It’s always fun to check out the Twin Cities during a flight arrival at MSP. However, it’s a bit less cool when I pass through a thick layer of brown air on the way in like I did today around 1pm. The shot above has Mendota in the foreground (coming in over Ft. Snelling from the east).
Here’s a landscape view of the air we breath.

The air is pretty calm in town today, which I imagine accounts for the accumulation of filth here rather than exporting it to our neighbors to the east in Wisconsin.
