After walking over a kilometer it was time to head into the forest, it was completely dark and I didn't see much of it. It seems like a crazy decision to try to walk the last 700 meters to the hash but it's also a kinda crazy decision to head out half an hour after midnight to try to reach a coordinate in the middle of a forest and then walk by foot for about six hours just to reach "nothing". (...)It was completely wet in the forest, small lakes and swamps had been temporarily created by the melting snow but this time it wouldn't stop me. My shoes got wet after just a few minutes and turned wetter since I had walked in deeper and deeper swamps. (...)I finally reached the geohash and it felt great.

What is this?
Geohashing is an adventure, comprising journeys to random places within a given area. Every day, effectively random locations are generated by an algorithm that achieves randomness using stock market data. It is a Spontaneous Adventure Generator. A set of coordinates is generated for each 1°×1° latitude/longitude zone (known as a graticule) in the world. The coordinates can lie anywhere in the graticule — in the forest, in a city, on a mountain, or even in the middle of a lake! Everyone in a given region 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.

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 next Saturday meetups, scheduled for 6 January 2018, will be based on the Dow’s opening price published at 09:30 EST (14:30 UTC) on Friday 5 January. 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.
