Found the lid broken and the box full of water. Log book was wet and unusable. Replaced the log book and rebagged everything. As stated in an earlier post, the log is about 2 foot long now and the stump is rotted away.

Box had half inch of water in it. Fortunately, previous finder replaced baggies (too new to be original), and the logbook survived! Both signs in clues are still there; it's the stump that's missing. Also, the fallen log is a mere 1 1/2 feet long now. Amazing what 6 years can do to a downed tree.
