To claim to be a well rounded cacher you must also have found at least one each of the ten types of cache listed below.

If your statistics are publically viewable that is sufficient proof. If not, you will have to list your qualifying caches in your log.

A checker has been added to make it easy to see if you qualify.
The cache itself is a short distance from the access gateway. Spoiler picture is available in the gallery. The cache is just off the forest track. It is placed in line with the "Leave No Trace" principles so there is no need to disturb the countryside in looking for this one.
