In order to claim a find on this challenge, you must find and log five of the seven oldest geocaches in Polk County. Cachers may sign a challenge cache's physical log at any time. However, the challenge cache may be logged as found online only after the log is signed and the challenge tasks have been met and documented. Finds on sufficiently old caches that are now archived will count as qualifiers. The checker below will tell you if you qualify.
