This was originally going to be a challenge cache, but we were unaware of new challenge regulations that made the challenge against geocaching guidelines. As a result, we decided to make this a multi instead and also have another unique initial character. An aerie is an eagle's nest, and we've frequently seen bald eagles soaring high above the area and suspect there is probably an aerie somewhere nearby. To find the final cache, follow the simple instructions below:
At the posted coordinates, you'll see six digits (ABCDEF)
At stage two, you'll see another six digits (ZYXWVU)
Let M=F+V+Z, N=B+C, O=X+V, P=U+E, Q=Y+A, and R=C+D+W
The final can be found at N 40º 24.MNO W 85º 58.PQR.
Please re-hide the container with the top facing down.
