What’s an EarthCache?

  •’s Definition: An EarthCache is a special place that people can visit to learn about a unique geoscience feature of our Earth. EarthCache pages include a set of educational notes along with cache coordinates. Visitors to EarthCaches can see how our planet has been shaped by geological processes, how we manage its resources and how scientists gather evidence to learn about the Earth.

  • The Society (GSA)
  • Established in 1888, The Geological Society of America provides access to elements that are essential to the professional growth of earth scientists at all levels of expertise and from all sectors: academic, government, business, and industry.

Viewer question from Louis Caplan on G+

  • Question… I’d like to set up an Earthcache (one of the 3 cache types I have not set out yet), but have had a hard time finding things “Geologically significant” to do the earthcache about. Any tips for finding such locations that could be used?

EarthCache Frequently Asked Questions via

  • How is an EarthCache different from a virtual cache?
  • EarthCaches are in effect a type of virtual cache. They have no physical container or log book. However, EarthCaches are different from other virtual caches in so much as they teach the visitor something about the site. An EarthCache is not just a scenic view or a locality. They present some lesson on how that place formed, about why that place is important scientifically or what that site can tell us about our planet.
  • Why do EarthCaches have to be virtual caches?
  • The object of an EarthCache is to learn something about our planet. The reward is the lesson, not the trinkets in the container. Also, many EarthCaches are being developed in places where it is against the law to leave a container, such as in National Parks and at Geological Monuments.
  • Who reviews EarthCaches?
  • EarthCaches all have one fundamental goal — to educate the visitor. This is judged by the EarthCache team, which is a small group of people internationally who review and publish the Earthcaches. The team all follow the same guidelines and rules.
  • Can we develop EarthCaches in National Parks and other public land?
  • EarthCaches can be developed on public land only if you have the prior approval of the local land manager. Most land managers, once they are told that concept and that no physical container will be left behind, are happy to have an EarthCache in their park, forest etc. We would suggest however, that you develop EarthCaches in partnership with the land managers, to ensure that sensitive areas are avoided, that multi-cache concepts are used with waypoints to keep people on trails and that cache-in-trash-out is advertised.
  • Caches of any description that are developed on public land without prior approval are undesirable, and on some land illegal.
  • What do I need to have people do to log an EarthCache?
  • As EarthCaches are educational, visitors should log some aspect of their visit that shows they have learnt something from their visit, like a direction, size of a feature etc. These answers can be emailed to the developer.
  • EarthCaches are virtual and involve no container, so why do I need permission to place an EarthCache on some public properties?
  • Advance permission is required to ensure that bringing people to a site does not cause a conflict with the management of that site. Many sites have multiple management issues, such as the protection of rare and endangered fauna, the protection of archaeological artifacts and the protection of a geological phenomenon. In many cases that protection has been obscurity (i.e. because people don’t know about it, they don’t visit). By placing an EarthCache at some public sites, we may cause a management issue and so the land manager needs to make sure that the EarthCache fits into their management plan. Furthermore, seeking permission has raised the positive profile of caching in the eyes of land managers, opening the way for all types of geocaching on those lands. We realize that seeking permission to place an EarthCache seems like a superfluous step to many, but it is truly as important as developing great logging tasks!
