This is a Bonus Cache for the Truckee Donner Historical Society Adventure Lab.
The geocache is not at the above coordinates.
The final location can only be found after successfully completing the five Adventure Lab stops. Four of them will contain partial digits you will need for the coordinates to arrive at the final cache location. The digits will be listed in the message after each Adventure Lab location stop is answered correctly.
If you have already completed the Truckee Donner Historical Society Adventure Lab you can access the needed coordinates information by going to the Journal entries on the TDHS Adventure Lab page.
