Your clue
"I once fed a city with flour from this river's power. My walls still stand in silence,
watching the water that once turned my wheels. Look for the number on my oldest remaining
stone arch — count from the left. That number is your key."
Need a nudge?
Sioux Falls had a historic flour mill that used the power of the Big Sioux River. Its ruins still stand within Falls Park — look for old stone walls near the water.

There are 3 main stone arches remaining. Count from the left — the answer is "THREE".

Your clue
"I connect two banks above the roaring water, a place where visitors pause to feel the
mist on their faces. Look for the plaque on my railing — the year I was built holds
the last two digits of your answer. Add them together."
Need a nudge?
You're looking for a footbridge — a pedestrian bridge that crosses over or very near the main waterfall at Falls Park. It's one of the best spots to feel the mist from the falls.
Cross to the main pedestrian bridge over the Big Sioux River at the falls. Find the informational plaque or date marker on the bridge railing. The year on the plaque ends in "19" — take those last two digits.
The last two digits of the year are 1 and 9. Add them together: 1 + 9 = 10. Your answer is "TEN".
