Multihash

The achievement can be claimed when you venture to multiple sets of coordinates on the correct day, and take photos of yourself containing the necessary proof, that is, you grinning like an idiot, showing the date and the location of each of your hashes.

The Multihash achievement could require traveling more than 150 miles in one day, or not require travel at all, depending on your location. This achievement is hardest to get for those near the equator, but for someone traveling to the south pole, this might be very easy. Conceivably, a person standing on the south pole could get 360 geohashes without moving, given a geohash at the extreme south of a graticule. On 2008-02-27 Fell at -89.999896° effectively 11.7 Meters from the South Pole, so a quick 73.5 Meter walk would have allowed you to clam 360 hashs in possibly under 1 minute.

• Double Hash -- visit two geohashes on one day.
