Finally found out where some of our missing caches have gone,
all props for this cache are brand new, so have no fear when searching for the right container with the logsheet, probably pick the one that looks the newest! 
As this section of the trail is owned by the DNR, a geocache notification form has been submitted to the Fond Du Lac Parks And Planning Committee, who manage this trail. Caches placed on DNR property require approval by the land manager.
