Welcome to the Newark Earthworks Odyssey!

The Newark Earthworks are world-class ancient structures. Built by the Hopewell culture, the complexes here are the world's largest geometric, earthen enclosures. They dwarfed the size of other classical constructions such as Stonehenge, the Colosseum, or the Pyramids in Egypt. Tragically, only about 10% of the original structure survives. What remains, however, is on the shortlist for becoming a UNESCO World Heritage Site, the gold standard of cultural locations.

The stated coordinates for this mystery cache are not where you will find the container. Instead, they are parking coordinates for the Newark Earthworks and the starting spot for the corresponding Adventure Lab I published. To obtain coordinates for the container of this cache, you must work your way through the Adventure Lab. At each of the five stops, you will find information that will lead you to the coordinates for this mystery.

Make sure you have downloaded the app for Adventure Labs to begin your adventure. At the posted coordinates, you can launch the Adventure Labs application and you will see the starting point for Newark Earthworks Odyssey. Alternatively, you can click on this link to take you directly to the adventure. Or you can scan the QR code below:
