At the given coordinates, there is an old church ruin from the middle age. The church's name is Gudleifs Asaka, and it was used until the 16th century, when it burned from a lightning strike. The stones from this church was used to rebuild the Skedsmo church which you can see from the ruin (on the other side of the valley).
PLEASE DO NOT WALK ON THE FIELD! To reach the ruin, enter at N59° 58.872 E11° 06.168 and follow the grass path.
From the sign by the ruin and the surroundings, you can calculate the coordinates for the cache box:
Number of white flag poles by the ruin: B
Number of black flag poles by the ruin: C
The inside of the ruin is 10,7 m long and E,5 m wide
The church was built in the century that starts with the year 1F00.
The church ruin was renovated in the year 19GH
A human skeleton was found here in the year 1IJK
L = G + F
M = K + B
The cache box is located at N59° KI.CLM E011° CE.JHJ
To find the cache box, go back to the road. Follow the road until you are about 50 metres away from the calculated coordinates. A new cache container is placed at the same spot as the first box.
Near the cache box, there is a burial place from the 19th century. In the beginning of the 19th century, there lived an officer on the farm Asak Mellem with a son that died 22 years old. The parents were so sad that they didn't want to bury him on Skedsmo church, it was too far, so they created this burial place. Other family members were buried here later.
Stroller/wheelchair: If you have a strong person to push and big wheels, you can get to both the spots. But the cache box itself is out of reach with a few metres.
15th of April 2012: The description, waypoints and the box itself is updated. The number of trees has changed, so I have dropped that part. Also, the number of openings in the ruin can be understood differentely, so I have skipped that part too. I have updated the waypoint for the grass path. I have also put a new cache container together with the old one, because the old one was leaking.
