TrailRun: Unfortunately I have to archive this cache, and the container and marker will picked up before May 1, 2006.
A lot of people really enjoyed this one, not because of the cache, but because of the waterfall and nice surroundings in this less visited part of Waterfall Glen. I'd recommend a visit to the established trails in this area whether or not there is a cache to find.
It's in an area the DuPage Forest Preserve has designated as not being available for GeoCaches (all of southern Waterfall Glen), so I did not attempt the permit process, because it's pretty clear the cache would not be allowed at this location.
