Since the rest of the party didn't have to come back up to claim (aka beta test) the cache, they were perfectly happy to let me wander off to hide this cache. Take it up with them when you come back from this find. I won't name them, but one is listed above and the rest are in plain plain sight.
FYI: There were no rocks, ledges or climbable trees so the terrain is only a 3.5. Sorry.
