As the banner says, if you qualify, you can log it. All OCNA Challenge caches are locationless type, arranged as Geo-Art in The Gulf of Mexico.They are all "unknown" (?) caches, owned by a special Admin account, OCNAChallenges. Do you have an idea for one? Feel  to contact us.

Variety Show Hider: OpenCaching North America currently has 14 cache types available to be found and hidden. see them here

For this Challenge create and hide 4 different cache types. Caches must be OCNA Exclusive to qualify.

Verification: Please post your qualifying hides with your log, preferably in the http://coord.eu/OUXXXX format, and also keep in mind you can link to cache pages using our cache log editor, although is not mandatory. To see if you qualify, you can just look through your list of hides in your profile. It is also possible to do a "my hides pocket query" on our site! (follow these instructions, but substitute your hidden caches, rather than your finds ) and that .gpx file is easily imported into GSAK, or any similar stats program. We recommend a "gpx gc" file, and we also recommend GeoGet as a free alternative to GSAK, should you not be a paid full version user of GSAK.
