The cache is NOT at the posted coordinates. This is the Bonus Cache for completing the “Little Known Memorials’”Adventure Lab Cache. You will discover the coordinates for the Bonus Cache while completing the Adventure Lab.
If you haven’t completed an Adventure Lab before, you will enjoy seeing and learning about places you are visiting, however, currently, you will not find Adventure Labs on the geocachng.com website. In order to complete them, you need to download the free Adventure Lab app onto your smart phone. The adventure will have several locations where you need to get close enough to answer questions asked. Very similar to Virtual caches, but you need to be in close proximity to the location in order to log it.
