Thanks to SlashDot that I found this very interesting site / sport.

The stash is located under the root of a fallen tree in woods bit over 1 km south from Keinukallio ski centre. It should be quite easy (2/2) to find with picture clues and co-ordinates. There is path passing about 50 m from the stash. Stash is marked with blue paper ribbon attached in nearby small tree. See pictures for more clues.

Stash contains:
* Letter in Finnish and English
* Sunglasses
* 1 key ring
* 1 bag of xylitol chewing gum
* 1 box of freshing mints
* Logbook and pen

Position information should be very good. My Garmin III+ claims averaged position accuracy to be 3.2m ( see photo below). I would be happy to hear from you if you find the stash.

Stash is now easy to access but when the snow comes, I would guess that it will be very difficult to access during January-March depending how much snow there will be on the top of the cliff I put the stash.

Happy Hunting.
