xckd is a comic strip by Randall
Munroe that is described as "a webcomic of romance, sarcasm,
math, and language." Randall, himself, is a
fan of geocaching as well as a computer and math geek.
In that spirit, he created geohashing, a "...method
for finding an effectively random location nearby and visiting it:
a Spontaneous Adventure Generator."
The image below is the comic strip that started it all. The
Algorithm.
Fans of the comic decided to try it out. They started
calculating daily hashpoints and exploring. A wiki was created for
people to share their experiences just as geocachers log their
finds.
Like all geek activities, it wasn't long before achievements
were created. One of them is the Hash
Collision Achievement where the day's geohash coincides with a
pre-existing geocache.
To find this cache, you will need to:
- Visit the geohashing
wiki and use one of the tools provided to calculate the hash
coordinates that would have caused the collision in the "Hash
Collision Achievement" directly above.
- Make your heading 245.4 degrees true, distance 137.1 feet
Please calculate the range/bearing at home and do
not attempt to visit the hash coordinates directly
as they are on private property.
If
you go on any future expeditions, please post a note here with the
date and graticule. I will add your hashpoints as waypoints on this
listing.
Note: The Algorithm generates coordinates in
DD.dddddd format, so you may want to convert to DD MM.mmm as
needed.
