To get to this one you will have to explore the Burley Park and walk past the Burley Dam. I have been trying to research more about this stone dam with no luck.
The Cache container is a camouflaged plastic tub. You may get wet crossing the creek. Be careful and don't fall off the Dam if you decide to climb it.
Congratulations to blumpkinman, Bluecanoe, gearguru, and mrdauber13 for the FTF party.
