Note: the cache is not at the posted
coordinates but is located at a distance no greater than 250 meters
from them.
This is what you have to do to get the cache: run around like a
chicken without a head. Along a circle. Along a specific circle of
radius 250 meters whose centre is at the posted coordinates. During
your run, you will bump into six trees, each with a copper tag
indicating a letter and a digit. Each tag will be facing the centre
of the circle. After having bumped into all six trees, run for the
cache at a distance of ABC meters from the centre of the circle
with true North bearing DEF degrees.
On your mark, get set, chop!
If you need a hint, check out the
tag position diagram. North is not indicated, and the diagram
has been rotated. It is to scale.
