This cache is on private property (with permission from John Sommerhof) and in an Illinois Nature Preserve. Please make sure you follow the rules of the area and the directions for this cache carefully. One of the rules of this area is to stay on the trails and do not bushwhack. So please stay on the trail until you get to the cache. The property owner saw some logs mentioning going off the trails and asked to me to warn people they need to stay on the trail.
This is one of three caches I have placed in the Olin Nature Preserve. When I was a kid, I lived near here and I hiked and explored this place all the time.
No dogs, pets, bikes, etc are allowed in the Nature Preserve. It is private property (owned by the Nature Institute), but open to the public. All plants and other features are protected by state law.
The area is closed between mid November to mid March because the area is used by bald eagles as a night roost. The cache will be disabled during this period. The owners have asked me to tell you in addition to closing for the Eagle Roost, they close the preserve on certain occasions for management and all visitors should adhere to the signage at the entrance to the preserve.
To get to the preserve, go Route 3 and get off on Levis Lane (N38 55.754 W90 12.774) and head back to the Nature Preserve. Park at N38 55.080 W90 13.449. Do not enter the preserve any other way, particularly from the River Road. You will encounter No Trespassing signs and entering this way is trespassing.
The suggested order for the caches are Overlook, Beaver Falls, and then Olin Nature Preserve.
After you go to Beaver Falls Cache, head back. When you come to the road, head towards the cache. There is a foot bridge across the creek near the cache. Go across the bridge. After you find the cache, this trail will get you back to the parking lot. There are some forks, take them and use your GPS to figure out which fork.
The cache contains a log and pencil. This is the 85th cache I have hidden. I did not have a real good fix, but looking at the hint and knowing it is close to the bridge, will make it easy to find.
