-Rusty-: Archiving at the request of the MKC. There is public access to this site but the land is not public. The concern is that someone could get hurt or damage the fragile ecosystem inside the sinks.
I will be adding it to the Michigan Cache Rescue list for removal by the next visitor, the rescue list can be viewed at www.mi-geocaching.org
It was suggested that the cache owners could retrieve the cache themselves and there are similar sites nearby that are public. It should still not actually be placed down in the sinks.
