The objective of the cache is to bring people to a pleasant walks in Seurasaari outdoor museum and recreation area. Those of you who are in this game to quickly find as many caches as possible are free to use whatever shortcuts they can. No need to walk all the route.
This cache will take you perhaps up to a couple of hours. You'll have to be prepared to walk for about three kilometres and find three locations. The cache used to be a black film canister, then it was converted to virtual and is now hopefully in its final form as small sized plastic box.
At the first stop - IN SUMMER
find out when 'Jouni' was here. Subtract 1050 from that year to find out the XXX in the second latitude N60° 10,XXX. Then subtract 1946 from the same year to get YYY. The second longitude is E24° 53,YYY.
The first stop is not available when there is snow on the ground and Jouni's signature has faded over the years. Therefore an alternative starting point is given.
At the first stop - IN WINTER - Location N 60° 10,604 E 024° 52,967
you're looking for a tiny metallic plate - about the size of child's hand. There are two numbers on plate (and nothing else). Subtract 67 from the upper number to get XXX and subtract 2834 from the lower number to get YYY. Then place XXX and YYY to the formulas given in Summer start chapter.
At the second stop
you'll find a mechanical structure. Walk around the structure and count the corners. Then walk around it again and count the windows. Windows that is, not windowpanes, and all windows are same shape and size. I.e. Ignore those that differ from majority. Multiply the number of corners by 10 and then subtract a 10. There you have final XXX. As for YYY, multiply the number of windows by 8 and then add an 8. This will give the YYY for the third and final stop at N 60° 11,XXX and E 24° 53,YYY.
At the final stop
search for a small plastic container that can contain geocoins and smallest TBs, but there's no room for swaps. Sign the logbook and tell what did you like about the cache & Seurasaari. And please ensure that box is well-hidden when you leave.
