The cache is not at the posted coordinates!
You must complete the associated Geocaching Adventure Lab to obtain the coordinates to this cache.
Open the free Adventure Labs app (available in the same place you got the geocaching app), login with your geocaching name, and play the Adventure History's Crossing Place - A Bridge to the Past Adventure Lab. If you are reading this cache page on a mobile device that has the Adventure app installed, that link will take you straight to the Adventure. The posted coordinates for the Adventure are the same as for this cache. PRO TIP: Remember to enter the coordinates for this cache after you get them at the last AL stop. When you complete all of the locations (Lab Caches), you will be rewarded with the actual coordinates for this cache which will appear in the last View Journal Entry of the Adventure Lab. Then enter those coordinates into your device, find the final and then sign the log!
