OzGuff: The huge stump under which this cache was hidden had fallen into the lake. I was pretty sure that the cache had floated off but saw it laying on the ground not far from the stump. It was open and the contents were spread about the area. I picked up all I could, but found no logbook. (And the geocoin listed as being in the cache was also not there.)
Since the cache was compromised and the hiding spot no longer available I decided to archive the cache. Thanks to all who visited!
