Fish,
I agree with Barry "Hiker"; I think you just have to try again. I think we have to accept some percentage of lost caches. I lost one to a flooded stream. The Narrows cache near Pine was apparently pilfered between my visits there, as I found only a plastic bag and a pencil on my last visit. I have come to suspect that ammo boxes may be attractive to some people.
Anyway, keep trying and good luck.
