This cache is traditional in the sense that it is hidden at the listed co-ordinates, and can be logged in the cache logbook when found. It is a multi, in that it can only be logged online if you have already found the "Not Mush Room" opencache - which provides the code to open the container which contains the CC for this cache. It is also a waypoint for a terracache of the same name. The CC contains two numbers, two lower case letters and two upper case letters.
