CACHE IS NOT LOCATED AT THE POSTED COORDINATES.
This is a bonus cache for those who successfully complete the Great River Landing Adventure Lab. Upon completion of that Adventure, coordinates to find this cache will be provided. (Tip: if you don't see the coordinates, you may have to look in the Adventure's Journal.)
The Great River Landing Adventure Lab is playable with the Adventure Lab app on smartphones and internet-capable devices. An internet connection is required to complete the Adventure.
Most of the Great River Landing Adventure Lab is wheelchar accessible on a paved path; this cache, however, is not. Depending on the time of year and recent weather, this could range from T2 to T4.5. There is a walking path until about 50 feet from GZ, then it could get muddy.
