Bluff Country, Minnesota
The Root River valley, the Mississippi bluffs and the ridge roads above them. 25 roads, 1,000 miles and 1,335 corners across Houston, Fillmore, southern Winona counties — the southeast corner of the state, where the last glaciation stopped and left the rivers to cut the hills instead of ice flattening them.
Each road below is scored on the same five-point curviness scale, measured from the road geometry rather than guessed at: CS-1 is a road that mostly goes straight, CS-5 turns almost continuously.
