This bonus geocache is NOT at the posted coordinates.
First, you will need the Adventure Lab app available from the app store on your smart phone.
You will then need to complete the "20 Years of Geocaching - Estes Park" Adventure Lab in order to get the final coordinates for this bonus cache.
You will have 5 stops on the Adventure Lab experience that you must complete before you receive the coordinates for this cache. You may retrieve the coordinates at anytime after you have completed the tour by viewing the journal of the "20 Years of Geocaching - Estes Park" Adventure Lab series.
The coordinates for this Bonus Cache will be listed on the final journal entry. Note: If the app skips displaying the fifth journal and congratulates you on completing the experience, you must go back and review the journals to get the coordinates in the last journal entry.
