Cache is a sign-only 35mm film canister. You'll need to bring your own pen. It's somewhat challenging to get to, so please be careful. Terrain rating would be a 1 except for the final couple of feet. It can be very tricky when wet! Please don't knock the container out with a stick or something, you really need to be able to put it back and hide it properly and that won't work unless you can see it.
While you're here, there's a nice small park (and another cache) just across the street. Closer to this cache, behind the fence to the west are leftover pieces of some sort of water district facility. Oddly enough, there is also a bicycle wheel up in a nearby tree.
