This cache is a Challenge Cache:
It is at the posted coordinates, even though it is an "unknown" Cache type.
You are not allowed to log a "find" without proof that you qualify by completing the caching related "Challenge" below, but you can make a write note.
Challenge:
To log this cache, you must have found and logged one hundred (100) or more Caches with the difficulty rating 5.
You can attach a proof to your log (optional).
Logs that don't fulfil this condition will be deleted without any comment.
As the owner of a challengecache I have to fulfil the cache condition myself.
