The Cache is not at the posted coordinates! The coordinates do send you to a point near the main gate of the Historic Green Cemetery.
You must complete the associated adventure lab to obtain the coordinates to this cache, as it is a bonus for completing the Adventure Lab "Veterans Monuments." Read carefully after successfully answering the questions at each location. You will find the final coordinates after visiting the final location.
Use the Groundspeak Adventure Lab app and locate the link for "Veterans Monuments" or scan the QR code down below.
