The Adventure Starts Here
Geohashing is a game of spontaneous adventure generation played around the world since 2008. You will explore random locations, meet fellow geohashers, brave the elements, unlock achievements, and then come back here to document your expedition.
Do you want to hit up the Portland geohash with Alison and me? Today. Like right now. We're going to drive to your house if you don't answer.

How to play?
- Create or log in to an account (returning after a break? all accounts created before 2020-02-02 were deleted; you'll need to sign up again)
- Use a coordinate calculator to give you a pair of GPS coordinates
- Go there (or as close as you can safely/legally get)
- Write about your expedition!

How does Geohashing work?
Every day, effectively random locations are generated by an algorithm that derives randomness from stock market data. A set of coordinates is generated for every 1°×1° latitude/longitude zone in the world, or graticule. The coordinates might be in a field, a forest, a city, up a mountain, or out at sea! Everyone in a quadrant of the globe gets the same set of coordinates relative to their graticule.
The generated coordinates are used as destinations for adventures, à la Geocaching, or for local meetups. After the fun, please document your expedition: The rest of us would love to read your story, see your photos, and cheer your success (or commiserate with your failure)! Join the other 'spot spotters', be out standing in your field and use this wiki to document the daily coordinates (geohashes) you’ve been to or tried to reach.
The daily coordinates are repeated for each degree all round the planet, but there is also a single globalhash, rare, valued and much harder to reach.
- Happy first anniversary of the wiki's revival, if you count the 'birthday' as the date of the first user account creation plus the announcement on IRC!
- The subdivision geohash is an achievement now.
- SIGSTKFLT is doing a slow rollout of Ribbon2. Add a comment if you see any problems.
- It's now possible to upload and embed GPX tracklogs of your expeditions.
- Dan Q is attempting to resurrect the wiki. Don't assume he knows about the problem you've discovered; let him know.
Official xkcd meetups
Official xkcd meetups happen every Saturday afternoon at 4:00 p.m.(*) at that day’s normal geohash coordinates. It is considered a Saturday meetup if you are there at 4:00 p.m. or if you meet people, but you are most likely to encounter other readers of xkcd if you go at the designated time. Bring games!
You're encouraged to geohash on any day of the week that the coordinates are accessible to you, but if you attempt one meetup all week, make a little extra effort to have it be on Saturday. All meetups start at 4:00 p.m. or as designated on the graticule page.
There's even an achievement for making it to 100 Saturday meetups.
*In some areas, 4:00pm is too close to sunset during the winter, so earlier meetups are often more appropriate. See individual graticule pages for local conventions.
Recent and Upcoming Coordinates
The coordinates for the Saturday meetups on 10 April 2021 are now available. The coordinates for the next Saturday meetups, scheduled for 17 April 2021, will be based on the Dow's opening price published at 09:30 EDT (13:30 UTC) on Friday 16 April. See timeanddate.com to convert this time to your local time zone.

Gallery of Recent Expeditions
The gallery for each day is added to this page automatically, but pictures are selected to the gallery by us. Any geohasher is welcome to add a picture from that day. Just add your image name in the list at the “add yours” link. If the gallery hasn't been started yet, copy the format from the previous day, or read the how-to. Please also write an account of your expedition, even if only a short one, so that people can click the link on your picture and find out more.
This section documents hash expeditions that geohashers wish they could make, but have not been able to for the reasons stated.
