Archiving a cache removes the listing from public view on Geocaching.com. This action is usually taken when a cache owner does not intend to replace a cache after it has been removed. As an alternative to archiving, the cache owner can temporarily disable their cache if they plan to provide maintenance on the cache or replace the container within one month.
These are icons on a cache detail intended to provide helpful information to geocachers who wish to find specific types of caches. These icons represent unique cache characteristics, including size, whether the cache is kid friendly, if it is available 24 hours a day, if you need special equipment and more.
A Premium Member feature that can be used to group cache listings in whatever way you like. You may want a bookmark list of caches you intend to find this weekend, or perhaps an “all-time favorite” list you can share with friends.
Bring Your Own Pen/Pencil. An acronym often used by cache owners to communicate to other geocachers that you will need to bring your writing utensil in order to sign the cache logbook.
A shortened version of the word geocache.
C&D/cache and dash
A term used when parking up next to a geocache’s co-ordinates, then moving on very quickly. Also known as a P&G (park and grab).
Cache In Trash Out is an ongoing environmental initiative supported by the worldwide geocaching community.
Did Not Find. An acronym used by geocachers to state that they did not find a cache. This is also a type of online log on Geocaching.com and is useful for alerting cache owners of potential issues. Cache owners who repeatedly receive “Did Not Find” logs should check to see that there cache has not been removed.
Geocaches are rated in two categories, each designated on a 5-point scale. Difficulty relates to the mental challenge of finding a cache and terrain describes the physical environment. A 1/1 difficulty/terrain rating would the easiest cache to find, while a 5/5 difficulty/terrain rating would be the most difficult.
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.
An Event Cache is a gathering of local geocachers or geocaching organizations to discuss geocaching. The Event Cache page specifies a time for the event and provides coordinates to its location. After the event, the cache is archived.
First to Find. An acronym written by geocachers in physical cache logbooks or online when logging cache finds to denote being the first to find a new geocache.
A unique identifier associated with every geocache listing. The GC Code starts with the letters “GC” and is followed by other alphanumeric characters.
A container hidden that includes, at minimum, a logbook for geocachers to sign.
Geocaching is a worldwide game of hiding and seeking treasure. A geocacher can place a geocache in the world, pinpoint its location using GPS technology and then share the geocache’s existence and location online. Anyone with a GPS unit can then try to locate the geocache.
A person who takes part in the hobby.
A Geocoin works similarly to a Groundspeak Travel Bug® in that they are trackable and can travel the world, picking up stories from geocache to geocache. Geocoins are often created as signature items by geocachers and can also be used as collectibles.
GPS stands for Global Positioning System. It is a system of satellites that work with a GPS receiver to determine your location on the planet. GPSr = Slang for a GPS receiver. Equipment to receive GPS signals for use in navigation.
GPX (GPS eXchange Format)
A specific file format available when creating a Pocket Query. A Premium Member feature, the GPX file format has specific geocaching information that can be used by supporting applications.
The point where your GPS device shows that you have reached the cache location. At Ground Zero, you are zero feet (or zero meters) away from your destination.
A hitchhiker is an item that is placed in a cache, and has instructions to travel to other caches. Sometimes they have logbooks attached so you can log their travels. A travel bug is an example of a hitchhiker.
Latitude and longitude create a waypoint. Latitude is the angular distance north or south from the earth’s equator measured through 90 degrees. Think of latitude as rungs on a ladder.
Letterboxing is another form of treasure hunting using clues instead of coordinates. In some cases, the letterbox owner has made their container 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
The original download format for the search results page on Geocaching.com.
Locationless (Reverse) Cache
A Locationless Cache could be considered the opposite of a Traditional Cache. Instead of finding a hidden container, you locate a specific object and log its coordinates. These have evolved into waymarking.
Latitude and longitude create a waypoint. Longitude is the angular distance measured on a great circle of reference from the intersection of the adopted zero meridian with this reference circle to the similar intersection of the meridian passing through the object. Think of the long lines running north and south.
A Mega-Event cache is an Event Cache that is attended by 500+ people. Mega-Events offer geocachers a day of planned activities. There are often several days of additional activities surrounding a Mega-Event. These large events attract geocachers from all over the world and are often held annually.
A small geocache container, quite often of a similar size as a 35mm film canister.
A non-geocacher. Based on “Muggle” from the Harry Potter series, which is a non-magical person. Usually this term is used after a non geocacher looks puzzled after befriending a geocacher searching for a cache, or when a non-geocacher accidentally finds a cache. Geomuggles are mostly harmless.
A Multi-Cache (“multiple”) involves two or more locations. The final location is a physical container. There are many variations, but most Multi-Caches have a hint to find the second cache, and the second cache has a hint to the third, and so on.
The “catch-all” of cache types, this form of geocache may involve complicated puzzles that you will first need to solve to determine the coordinates. Mystery/Puzzle Caches often become the staging ground for new and unique geocaches that do not fit in another category.
A geocache container that is no bigger than a thumb nail. Usually quite hard to find and even harder to roll up the log book.
A Premium Member feature, a Pocket Query is custom geocache search that you can have emailed to you on a daily or weekly basis. Pocket Queries give you the ability to filter your searches so you only receive information on the caches you want to search for in either a GPX of LOC format. This feature lets you download up to 500 caches at one time.
Volunteers from all over the world who publish the cache listings on geocaching.com.
Hints for geocaches are encrypted using a simple format where each of the letters are rotated 13 characters up or down in the alphabet.
(letter above equals below, and vice versa)
An item unique to a specific geocacher that is left behind in caches to signify that they visited that cache. These often include personal geocoins, tokens, pins, craft items or calling cards.
A spoiler is information that can give details away and ruin the experience of something. For example, telling someone the end of a movie before they see it. In geocaching, a spoiler gives away details of a cache location and can ruin the experience of the find.
An acronym often referred to as standing for ‘Stuff We All Get.” It includes the trade items left in caches by geocachers.
Thanks For The Cache. An acronym written by geocachers in physical cache logbooks or online when logging cache finds.
Thanks For The Hide
Took Nothing. Left Nothing. Usually written in cache logbooks by geocachers who do not trade for material contents in a cache.
Took Nothing. Left Nothing. Signed Logbook/Took Nothing. Signed Logbook.
Tools of the Trade. An acronym used for any of the tools that might be used to search for/retrieve/find/log a geocache.
This is the original geocache type consisting of, at minimum, a container and a log book or logsheet. Larger containers generally include items for trade. “Nano” or “micro” caches are tiny containers that only hold a logsheet. The coordinates listed on the traditional cache page provide the geocache’s exact location.
A Groundspeak Travel Bug is a trackable tag that you attach to an item. This allows you to track your item on Geocaching.com. The item becomes a hitchhiker that is carried from cache to cache (or person to person) in the real world and you can follow its progress online.
A Virtual Cache is about discovering a location rather than a container. The requirements for logging a Virtual Cache vary—you may be required to answer a question about the location, take a picture, complete a task, etc. In any case, you must visit the coordinates before you can post your log.Although many locations are interesting, a Virtual Cache should be out of the ordinary enough to warrant logging a visit.
A watchlist is a list of users that are watching a specific Travel Bug or cache. Each user receives a copy of each posted log via email.
A waypoint is a reference point for a physical location on Earth. Waypoints are defined by a set of coordinates that typically include longitude, latitude and sometimes altitude.Every geocache listed on our website is a waypoint. Geocaching.com generates a unique “GC Code” associated with every geocache listing.
These are caches that use existing web cameras placed by individuals or agencies that monitor various areas like parks or business complexes. The idea is to get yourself in front of the camera to log your visit. The challenging part is that you need to call a friend to look up the web site that displays the camera shot. You will need to have them to save the picture in order to log the cache. If you’re a tech-head you could save the image yourself by using a wireless modem and a laptop.
The most current geodetic datum used for GPS is the World Geodetic System of 1984 (WGS84). The significance of WGS84 comes about because GPS receivers rely on WGS84.Geocaching uses the WGS84 datum by default. We also use the format HDDD MM.MM, which is a standard for GPS receivers (like the eTrex).HDD means Hemisphere and degrees. MM.MM are minutes in decimal format.
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.
