I'm Mark and I live within the London West graticule.

I'm hoping to put some more detail on this page soon, but for starters I discovered Geohashing via the T-Mobile G1 app when searching for xkcd apps and it merges my fondness for experimental travel and xkcd. Perfect.

After weeks of joking and threats to friends I finally achieved (and failed) my virgin Hash Attempt on May 31, 2009 and have the appetite for more. Unwittingly I might have set a few hares running with the distance - more detail on my talk page and that of the attempt itself, linked below.

I've listed them per expedition in the table above, so this list recognises only the first time that each of them was achieved, in chronological order:


Norsemark earned the Public transport geohash achievement
by reaching the (51, -0) geohash on 2009-06-21 via FCC train, Northern Line tube, DLR light railway & rail replacement bus!.

Outstanding ambitions[edit]

Being based in the corner hundredth of my graticule is a good opportunity to claim some early achievement scalps, so for starters I hope to achieve the following:

  • Multihash achievement, most likely in London East graticule when the latitude decimal is smaller than 0.1° and the longitude decimal is greater than 0.8° (approx once every fifty days)
  • Consecutive Geohash Achievement, probably when the hashpoint in Northampton is close, likely on days when the latitude decimal is less than 0.2° and the longitude decimal is smaller than 0.1° (again, approx once every fifty days)
  • Minesweeper achievement, probably by reaching both London East and Northampton
  • to defeat Mother Nature and earn the MNIMB achievement

Failed ambitions[edit]

I don't mind a bit of brutal honesty. What doesn't kill me will only make me stronger. These are things I'd planned to do but didn't

  • to not achieve the Mother Nature's Bitch consolation prize again before I've completed my 5th attempt (listed after #1 was a MNB)
