I have been seeing “Challenge of the Century” cache series pop up in areas where we have traveled. I’ve been thinking about several of the challenge caches we have in our area and some of them make it so that you limit your finds to spread them out over a time period. Well, here is a challenge that does not limit how many you get in one day. You can work on all 8 challenges at once: Challenge of the Century: Earthcaches; Challenge of the Century: Traditionals; Challenge of the Century: Multi; Challenge of the Century: Virtuals; Challenge of the Century: Unknown (Puzzle); Challenge of the Century: Letterboxes; Challenge of the Century: Events and the Challenge of the Century: Lucky 7. Your goal for this cache challenge is to have found one hundred (100) Unknown caches in order to log this cache. Groundspeak HQ is also considered an Unknown type so will be included in your total found. Unknown (puzzle) caches are sometimes the hardest caches to figure out. Some are very easy internet research, some mechanical, some sudoku, some mathematical, some electrical, some number sequence, and some cryptic. They require the use of the noggin or someone else’s noggin.
To know where you stand, go to your public profile and click on geocaches. It divides up your finds into each type of cache. If you have found 100 Unknown caches, you can go log this cache as a find.
LOGGING REQUIREMENTS: You must have a minimum of 100 Unknown cache finds to be able to log this cache. Please state how many unknown caches you have found in your log. I will verify by checking your profile. If you have not found 100 unknown caches, your log will be deleted. You will need to go out and cache to meet the logging requirement.
So, go out there and cache to your heart’s content and before you know it, you will have met the requirements.
