The posted coordinates will take you to a beautiful spot on the island in the middle of Lake Elizabeth, but you won't find anything there unless you are looking for geese to commune with. To learn the nearby final coordinates of this cache, you must complete Team Wolf Pack's Allegheny Commons Adventure. Once you have completed all stages of that Adventure Lab cache, you will have the information you need to find the nano which is the final container for this bonus cache. It can be found at:
N 40 27.ABD
W 80 00.EBC
If you haven't yet downloaded the Adventure Lab Cache app (which you will need to gain the coordinates for this cache), you can find it here:

Due to frequent muggling of caches in this park, the container is now a black magnetic nano. Please bring pen and tweezers.
We hope you have fun and enjoy the beauty of Allegheny Commons Park!
