To solve this puzzle, you will need to locate the objects shown in the photos, get the coordinates of those objects, and do a little math to find the cache coordinates. Note: The more accurate you can be at getting the coordinates of the bronze objects, the better it will be to attain accuracy of the final coordinates.
For the North coordinate of the cache, take the North coordinate of the bronze thumb and add 0.584 minutes.
For the West coordinate of the cache, take the West coordinate of the round bronze object and add 0.068 minutes.
The bronze thumb can be found in Riverfront Park near the Wenatchee Ice Rink. The round object can be found in Memorial Park.
If you would like to take a nice walk on the Riverfront Trail, it is recommended you get the coordinates of the bronze round object first, and then get the coordinates of the bronze thumb second. It's about a 3/4 mile walk from the bronze thumb to the cache. Or you can drive and park much closer.
