No box, no log book, your evidence of visit will be:
What kind of items did you find on the spot, and how many?
And what is the altitude?
In exchange for your skill and hardship you will find:
1. A fantastic view
2. A pond for swimming
3. The unknown summit of this forest reserve
4. A most charming trail
Peter and the pond
PS: Don't be mislead by the 1:50.000 map, or by the MapSource CD3 - Oslo, they are wrong about the summit position.
