Where 13 Should Be Traditional Cache

Tchingal: An action had been taken on this cache because of one of the following -
One or more of the following has occurred:
No response from the cache owner.
No cache to find or log to sign.
It has been more than 28 days since the last owner note.
As a result I am archiving this cache to keep from continually showing up in search lists and to prevent it from blocking other cache placements.
Should you like to resurrect the cache please create a new cache listing so it can be reviewed as a new cache.

7.15. Archive or unarchive a geocache
Archiving a geocache is meant to be a permanent action. Only community volunteer reviewers and Geocaching HQ can unarchive caches. This is done only in rare circumstances and only if the cache meets the current geocaching guidelines.

If a cache is archived by a reviewer or staff for lack of maintenance, it will not be unarchived.
