TheCoddiwompler: This cache appears to have been replaced by another cacher who is not the cache owner, and they left a "throwdown" container (which is discouraged). A “throwdown” is a container placed by a geocacher who cannot find the original cache
As noted in the linked Help Centre article, cache maintenance is the owner's responsibility and as the cache owner has not investigated the throwdown and re-enabled the cache listed as requested in a prior reviewer note, this cache is being archived.
