International EarthCache Day:
13 October 2024
Each year GSA celebrates International EarthCache Day on the first Sunday of Earth
Science Week.
EarthCaches are special geological locations anyone can visit to learn about our planet. On
International EarthCache Day, GSA encourages geocachers to visit EarthCaches and host
EarthCache-themed events or hikes. If you run an event or visit an EarthCache, post about it in
the Geocaching
forums, or share it on social media and tag it with #EarthCache. Geocaching.com offers a
special souvenir for people who log an EarthCache on the weekend of International EarthCache
Day.
For future Earth Science Week dates and themes (and thus, future International EarthCache Day
dates), please see AGI's
Earth Science Week homepage.
