# Geocache Types

## Traditional Cache

This is the original cache type consisting, at a bare minimum, a container and a log book. Normally you'll find a tupperware container, ammo box, or bucket filled with goodies, or smaller container ("micro cache") too small to contain items except for a log book. The coordinates listed on the traditional cache page are the exact location for the cache.

The general rule of thumb is, "If you take an item, leave an item, and write in the logbook." Some caches are themed, so make sure to read the description before going on a hunt.

## Multi-Cache (Offset Cache)

A multi-cache ("multiple") involves two or more locations, the final location being a physical container. There are many variations, but most multi-caches have a hint to find the second cache, and the second cache has hints to the third, and so on. An offset cache (where you go to a location and get hints to the actual cache) is considered a multi-cache.

## Project A.P.E. Cache

In 2001, twelve geocaches were placed in conjunction with 20th Century Fox to support the movie Planet of the Apes. Each cache represented a fictional story in which scientists revealed an Alternative Primate Evolution. These caches were made using specially marked ammo containers. Each cache had an original prop from the movie. Only a few Project A.P.E. caches exist today.

## Mystery or Puzzle Caches

The "catch-all" of cache types, this form of cache can involve complicated puzzles you will first need to solve to determine the coordinates. Due to the increasing creativity of geocaching this becomes the staging ground for new and unique challenges.

## Letterbox Hybrid

A letterbox is another form of treasure hunting using clues instead of coordinates. In some cases, however, the owner has made it both a letterbox and a geocache and posted its coordinates on Geocaching.com. If there is a stamp inside a letterbox hybrid, it is not an item intended for trade; the stamp is meant to remain in the box so that visitors can use it to record their visit.To read more about letterboxing, visit the Letterboxing North America web site.

## Wherigo Cache

Wherigo is a toolset for creating and playing GPS-enabled adventures in the real world. By integrating a Wherigo experience, called a cartridge, with finding a cache, the geocaching hunt can be an even richer experience. Among other uses, Wherigo allows geocachers to interact with physical and virtual elements such as objects or characters while still finding a physical geocache container. A Wherigo-enabled GPS device is required to play a cartridge. Learn more at Wherigo.com.

## Event Cache

Occasionally, local geocachers and geocaching organizations designate a time and location to meet and discuss geocaching. After the event the caches are archived.

## Mega-Event Cache

A Mega-Event cache is similar to an Event Cache but it is much larger. In order to qualify as a Mega Event, the event cache must be attended by 500+ people. Typically, Mega Events are annual events and attract geocachers from all over the world.

## Cache In Trash Out Event

Cache In Trash Out is an activity intimately tied to geocaching. While out there on a cache hunt, we collect litter along the trails and properly dispose of it. Cache In Trash Out Events are much larger clean-up events that involve and benefit the larger community.

## EarthCache

An EarthCache is a special place that people can visit to learn about a unique geoscience feature or aspect of our Earth. EarthCaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to EarthCaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth. For more information about EarthCaches, visit http://www.earthcache.org/.

## GPS Adventures Maze Exhibit

A GPS Adventures Exhibit Cache represents attendance at the GPS Adventures Maze Exhibit or a regional variation of this Exhibit. GPS Adventures Mazes are designed to teach people of all ages about GPS technology and geocaching through interactive science experiences.
