Welcome to OPERATION Worldwide Cache Hide. The purpose of this endeavor is to bring together geocachers from around the world to hide creative caches that will be mass-published on a specific day. This project is designed to promote creativity, community interaction, and some good old fashion fun. Below you will find all the details you need to know in order to participate.
Cache Creating Guidelines
WHAT TO CREATE
1.) Your hide must be themed to the current project subject.
2.) You may use the container type and size of your choice.
3.) You may make it any cache type you want.
HOW TO SET UP YOUR CACHE TO BE PUBLISHED
1.) Submit your geocache hide page to your local reviewer by no later than 14 days prior to the publishing date of the current cache hide project.
2.) Include the following note to your reviewer:
"The cache IS NOT ready to be published yet. This geocache is part of a series that will be published on May 4, 2025 @ 8am. If everything checks out, please set up the geocache for publishing at that time."
Note: Include other reviewer information about your hide such as container description and how it was hidden.
3.) Place the Official Logo at the bottom of the cache page.
4.) Use the current project prefix OPERATION SCI-FI at the
beginning of the title of your geocache hide to identify it as part of the geocache series.
Note 1: When you submit the cache page, make sure it is completed because when the reviewer sets up the publishing timer for the current promotion, they will lock the cache page and no further changes can be made until it’s published.
Note 2: The publishing time will be 8am no matter what time zone you are in.
What to do When
Your Geocache Gets Published?
1.) Change the HIDDEN date on the cache page to the date the cache was published.
2.) On the day your cache is published, email the cache page link to geocachingcentral@aol.com. At that time your cache hide will be
added to the official Bookmark List for the project and you will receive your Participation Badge.
