This cache is very similar to other hides that I've done. The cache may be muddy if it rained recently. The conatiner should be waterproof, but it has had issues in the past. It could also be extremely difficult to find if more than about half an inch of snow falls.

The conatiner is shaped like a bolt, where the head comes off and the threaded part contains the log. It may be difficult to open, if so try twisting.
