Hash collision achievement

Hash Collision Icon

Visit a geohash and, either through prior knowledge or pure chance, find a geocache on site of the hash. To count as being at the geohash site, the geocache must lie within sight of the circle of uncertainty of your GPS around the geohash coordinates. Placing a cache yourself does not count, unless you placed it before the coordinates of the geohash were announced, but you can place one that helps other geohashers later in the day win this award.
