If you solved this puzzle prior to 6/4/19, you will want to solve it again in certitude to get the updated coordinates. This cache is located in a dead fallen tree that goes over the creek that is often dry. You do not need to cross the creek. This seasonal stream originates just a few hundred feet up the ravine, gushing out of Troll Cave, located at N43 17.710 W091 49.091. Despite being seasonal, the water is generally clear, unlike many perennial streams in the area. Troll cave itself is a rather tight, muddy crawl - not for the claustrophobic.
The cache is not at the posted coordinates. To get the coordinates for the final, you must first seek the answer to this question:
What do we call a natural discharge of water from rock or soil onto the surface of the land or into a body of surface water?
