Official EarthCache™ Geocoin- Rock Strata

Let's celebrate geology!

These EarthCache geocions 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.

Dimensions:  Approximately 2 inches in diameter.
