I was astonished to find that it was only a block away from my cousin's house, which I'd probably been to four or five times! How could I have missed a giant glacial erratic boulder in such proximity? I had to investigate, so I began to take my leave.

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 30 September 2017, will be based on the Dow’s opening price published at 09:30 EDT (13:30 UTC) on Friday 29 September. 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.
