BarbarianB: Well, I'm pretty sure I found the tree the container was in.
There were a bunch of sticks in the hole, but no cache container.
I think the cache may have gotten washed out during a heavy rain and fallen into the creek.
The container may well be downstream somewhere.
Either way, I am not replacing it, especially with the "No Trespassing and No Hunting" sign blocking access.
Thanks to those who visited.
