This cache is placed with kind permission from Charterhouse.
The coordinates take you to a large tree at a track junction. You are looking for an orienteering punch.
- A = first digit of the two digit number written on the orange plastic punch
- B = second digit of the two digit number on the punch
- C = the number of metal spikes in the punch (use the punch to punch the pattern on a piece of paper to determine this, please don't break the punch by trying to look inside)
Final coordinates are: N 51° 11.(A+C)(C-A)(C+C-B) W 0° 37.(A+B)(A+B-C-C)(B-A-3) which is approximately 500m away along the path.
You are looking for a black 35mm camera film case. The cache is just off a path which is marked on the OS map but is NOT marked on the Geocaching app.
