Congrats to beach basenji for REALLY QUICK FTF!!!
3/19/2017 update. Well, I have tried to retrieve and service this cache twice. It's pretty bad when the cache owner can't find the thing, so I have to admit the fact that it's not where it's supposed to be and is lost in the dunes or someone's pocket somewhere. :-( SO. There's a new, and less portable cache in the same place with a dry log and more opportunity to bang about in the dunes! Have fun, cachers. and welcome to Ocean Shores! Still no hints, though, although if you've found Covert Crevasse, you have the right technique. :-)
2-11-22 update. The city has dug a drainage ditch right across the shortest approach to GZ. In order to score this smiley, you'll have to go down to the beach, cross the water flow, and hike back over the dunes about 500 feet to reach GZ now. I've changed the terrain difficulty accordingly, and also moved the cache a few feet into a smaller plant to make the find more rewarding for the effort. The coordinates have been updated to match, and the container and log have been replaced.
