The world’s first EarthCache turns eight-years-old today. Saying “Happy Birthday!” is as easy as logging an EarthCache. Chances are there’s one close to where you’re sitting right now. There are plenty of EarthCaches, think thousands and thousands, around the globe. But that wasn’t the case back in 2004.
“Earthcache I – a simple geology tour of Wasp Head” (GCHFT2) triggered a seismic movement in geocaching. The first EarthCache was located in Australia. It was placed by geoaware on January 10, 2004. Since then more than 17,000 EarthCaches have been published, popping up on every continent on the planet.
Each EarthCache must share specific characteristics before being published. There’s no physical cache. At every EarthCache, geocachers learn about the forces that sculpted the earth. EarthCaches showcase volcanoes, seismic fault lines, salt flats, bizarre rock structures and more. Each Earthcache reveals how scientists understand our planet.

To log an EarthCache geocachers must demonstrate to the cache owner what they learned about a specific geological feature. Geocachers might measure a rock structure or record a tidal movement. At the EarthCache “Olivine” in Hawaii, geocachers must answer questions about the unique green grains of sand.
EarthCaches are gaining in popularity as they grow older and more established in the geocaching world. Organizers are even hosting the first International EarthCache Event (GC33E6X) this year. It’ll take place in September near Portland, Maine, USA. More than 250 geocachers have already logged a “Will Attend.”
