"Roughly ten thousand years ago, raging glacial meltwaters created the broad valley of the Upper Mississippi River that we know today. They also helped form one of the river’s most famous and significant landmarks, known in Dakota as He Mni Caŋ (Hill Water Wood) and in English as Barn Bluff."1
It is the result of this glacial activity that allows us to enjoy the hikes and picturesque views. It also left behind geological features allowing for perfect geocaching hidey holes.
To score this cache you first need to solve for the final coordinates. To do that, follow these instructions:
- Find the signage titled "Kiwanis Stairway"
- Determine the year it was erected, this year = YYYY
- Calculate AAAA.. AAAA = 2201 + YYYY
- Calculate BBBB.. BBBB = YYYY - 635
- Calculate the final coordinates: N44 3A.AAA W092 3B.BBB
