This is a two-stage cache, the final cache is located a couple of
miles from the original coordinates. To find it you will need to do
a little reading and use some simple math skills.
Find an important year listed at the site. Divide by 1.9, round off
the decimals and add this to your latitude (North) coordinate. Take
that same year, divide by 1.12, round off the decimals and add this
to your longitude (West) coordinate. You will now have a new set of
coordinates and the location of the cache. Your quest should take
you past the longest uninterrupted granite wall in the world
(MCF-Saint Cloud) via the shortest state hiway in MN (MN 301).
