Let's celebrate geology!

These EarthCache travel tags are inspired by stratigraphy, making for an impressive design that captures the spirit of this unique (and sometimes very challenging) type of geocache!

Each year, The Geological Society of America celebrates International EarthCache Day on the first Sunday of Earth Science Week and the last Sunday of World Space Week.

The official EarthCache travel tag is trackable at Geocaching.com with a unique icon. 

Dimensions:  Approximately 35mm in diameter.
