This is a Bonus cache for completing the Eureka Tour Adventure Lab. DO NOT GO TO THE POSTED COORDINATES! The cache is NOT in the middle of the river, but a short distance away on dry land. In order to get the correct coordinates for the Bonus Cache, you must complete the Eureka Tour Adventure Lab. Once you've done that, you will be given the final coordinates at the last stop for the AL. Please replace the container and re-cover so it's not visible.
