New souvenir challenge:
The Science of Discovery

It’s 20 years into the 21st century and geocachers continue to be experts in the science of discovery. Recently, geocaching innovators have experimented in the Adventure Lab® to create new experiences. From interactive food tours to local trivia, cachers are formulating Adventures in new ways.

Let’s combine geocaching with Adventure Lab to create the perfect solution for discovery. April 12 through July 11, find Adventure Lab Caches and other geocache types to earn up to four scien-terrific souvenirs.

Join this challenge to learn more about Adventures and the undeniable chemistry between geocaching and science.

Our goal is to have a promotion that is both fun and safe. As such, we will continue to make any adjustments as needed so that the promotion is as inclusive as possible.

Where can I see my souvenirs?

Is this souvenir challenge in the Geocaching® app and the Adventure Lab® app?

Geocaching® app: The Science of Discovery will be in the Geocaching® app at the beginning of the challenge on April 12, and will be accessible until July 11, 2021. Go to your profile and tap on The Science of Discovery to see your progress.

Adventure Lab® app: The challenge and your souvenirs are not accessible in the Adventure Lab® app at this time.

My points aren’t adding up correctly, help!

  • If you change a Write Note, DNF, or other log type to a Found it log, it will not be recognized in The Science of Discovery.
  • You logged on Monday, April 12 before noon UTC (convert to your local time here). We suggest that you wait to log until AFTER Monday noon UTC—which in some places like New Zealand is Tuesday at midnight. Otherwise, the points will not count for the first week.
  • You saved a Draft on a Monday, April 12 before noon UTC.

If you have already posted your logs, select “View / Edit Log / Images,” then click the pen icon and “Submit Log Entry” on the website*. Your logs should now be counted towards your total.

*At this time, you can only edit your logs on,not in the Geocaching® app.

What does UTC stand for?

Coordinated Universal Time (UTC) is the basis for civil time today. It is the time standard (not a time zone) commonly used across the world. You can convert UTC to your local time here.

When I'm outside I'm happy. Besides geocaching I love gardening, hiking, cooking and spending time with my wonderful two and four legged friends. Got eight legs? Sorry, but please stay far away from me!
