Rolling off the South Dakota Mountains
This rather noticeable U shape in the mainline near Andover, SD is the result of the Milwaukee Road regrading the line to avoid the sharp rise up Coteau des Prairies. It is a rather sharp change in elevation, so much so that towns that sit on it get more snowfall on average than towns below. Your ears usually pop driving on US 12.
Anyway, the infamous 661 rolls west approaching Andover, SD.
