Geohashing is a game where you need to reach a random point that moves every day to a new location. The point can fall anywhere in its graticule. The Helsinki graticule is bordered by 60 and 61 north latitudes & 24 and 25 east longitudes. Rather large area in where the hashpoint may well end up to the sea, lake, rooftop or your own yard.
There's no hidden treasure at geohash location. The fun is in reaching the point itself. The coordinates for the next day are published at 4:30 p.m. (EET) - except for Sunday. The Sunday coordinates are published together with Saturday coords i.e. 4:30 p.m. on Friday. The hashpoint must be reached on the designated day, not earlier or later.
Today the coordinates fell in the Nuuksio National Park at an easy-to-reach location. I decided to leave a geocache there with a view to attract more people to geohashing. When you have found out enough information to determine the cache location, you can also see if a hashpoint falls nearby and seek it out. Keep an eye on the hashpoint map. Sooner or later the point comes close.
I didn't leave the cache-box to the exact hashpoint location to avoid geocollision. When you have figured out the correct hashpoint, do the following corrections and you'll find the cache:
