This is the story, as we know it today. Until 2000, the U.S. government degraded GPS signals using something called Selective Availability (SA). SA allowed the U.S. and its allies to use special GPS receivers to get very accurate location information while preventing civilian GPS receivers from having as much precision. In May 2000, SA was officially turned off (mostly because the U.S. government developed a way to degrade the accuracy of GPS to specific geographic regions). With that action, civilian GPS receivers that formerly were accurate only to about 300 feet became accurate to 30 feet. This new level of accuracy offered some interesting, creative
What equipment will I need?
CITO is the unofficial creed of Geocaching. When you go out
All that is needed to go Geocaching is online access to the website, a GPSr, and a sense of adventure. A GPS receiver (GPSr) is an electronic device that uses satellites to determine your location on the planet, accurate to around 30 feet.

If GPSr units are so accurate, why is this challenging? It is deceptively easy; it’s one thing to know where an item is, but a totally different story to get there! Plus, people use devious methods to hide their caches. The GPSr gets you into the grove in the forest, then it’s up to you to find the exact hiding spot.
Earth Day each April.
These coordinates are normally given in degrees latitude and longitude.
You can also use your GPSr to navigate from your current location to another location. Some units may have maps, built-in electronic compasses and even voice navigation, depending upon the complexity of the device. You won’t need to know all the technical mumbo-jumbo about GPSr’s in order to geocache. You only need to be able to enter the “waypoint” coordinates where the geocache is hidden. and follow them to the cache.

DNF: (Did Not Find) As in, did not find the cache.
It happens to everyone, so don’t worry. If you didn’t find the cache, try again on another day.
FTF: (First to Find) Bragging rights that you were the first person to find a newly placed cache.
When did
Geocaching start?
Three days after SA was turned off, Dave Ulmer posted a message in
slingshot. Earlier in the day, in the same newsgroup, Ulmer had
proposed a worldwide “stash hunt,” where people would post GPS waypoints (coordinates saved in a GPS receiver) on the Internet that would lead searchers to hidden goodies. While Ulmer envisioned thousands of stashes tucked in places all over the world, he had no idea how popular his idea would become.
By the end of May, in a Yahoo! Group devoted
to the new sport, a member named Matt Stumm who placed the first stash in Michigan, suggested that the sport be called “Geocaching”
in order to avoid some of the negative connotations associated with drugs and the word “stash”. (A cache is a hidden place where goods or valuables are concealed.)

Because Geocaching had such a nice ring to it, it stuck and now it is part of history.
Muggles: People you encounter on the trail who aren’t geocachers; a spin-off for non-wizards in the Harry Potter stories.
Swag: Goodies that you find in a cache.
TNLN: (Took Nothing Left Nothing) Just what it sounds
like. Simply signed the cache log, took no other action.
Travel Bug (TB): A type of hitchhike that you mark with a specially numbered dog tag purchased
from Travel Bugs can have specific goals (such as getting from point A to point B) or are just released into the world to see how far they can travel.

What is Geocaching?
About Michigan Geocaching Organization
MiGO is a nonprofit group that was established in 2002 with this mission:
MiGO’s goal is to serve as a forum for communication between Michigan geocachers, the general public, and land management officials, in a cooperative effort
to promote the sport of Geocaching, an appreciation of the outdoors, and good stewardship of the land and environment.
MiGO has become the “go-to group” for land managers with questions about Geocaching. We have prepared this information to help you become more familiar with Geocaching. If you have additional questions, we invite you to contact us, and we will work to assist you in any way possible.
Geocachers worldwide are helping to clean our parks and forests as they geocache.
Geocaching is an adventure game for GPSr (Global Positioning System receiver) users. Participating in a cache hunt is a great way for individuals and families to enjoy nature and find new places in their local community.
People from all walks of life are hiding, not burying, boxes in the wilderness, marking the exact coordinates on their GPSr and posting these coordinates on the internet at for other people with GPS receivers to find. These geocaches (also called ‘caches’ for short) usually contain trinkets for trade. When a geocacher finds a cache, they can take something out of it, but they need to leave something in trade. It’s like a secret worldwide swap meet. There is also a log book to sign in the cache, and then after returning home you log your find online at the cache page to share with others.
What are the rules of Geocaching?
• Take something from the cache. (Optional)
• Leave something in the cache. (If you took something)
• Write about it in the logbook.
• Log your find online.
MiGO promotes the Tread Lightly!® principles of outdoor ethics for responsible Geocaching in Michigan.
1. Travel responsibly
2. Respect the rights
3. Educate yourself
4. Avoid sensitive areas 5. Do your part
