There is only one stage to this cache, but due to the tree cover (and in order to avoid unnecessary bushwhacking), I am giving hints about where to head off the groomed trail.
Also, for those who want to avoid the additional challenge of figuring out how to find the entrance to the nature preserve, turn off the public road at N42° 14.563 W84° 44.547, and follow the signs from there.
Once you’ve parked, plan for about a mile hike (round trip). When heading out to the trails, remember to “think green”.
You’ll want to stay on the main trail until you get to N42° 14.316 W84° 43.976, where you’ll head under a maple tree in the treeline, directly across from a bird house. (See photos below for hints/GPS check info.)
When you emerge from the treeline (into the corner of a rectangular shaped field), you'll see a birdhouse directly across from the trail at the edge of the woods. When you get to the birdhouse, you'll see that it's marked with #18E. (There is also a red ribbon tied at the base of its post.) See the photo below for GPS check info.
The trail to the cache cuts into the woods between birdhouses #18E and 17. (If you take the same path I did, you’ll pass a HUGE grapevine not far from the entrance of the trail.)
The cache container is a tall Rubbermaid container (about the size of a box of saltine crackers), completely transparent, except for a bit of blue trim on the lid. The cache is easily visable from about 15’ away in several directions, so there is no need to disturb anything while searching for it.
