Geocache Description:

A mathematical challenge...


The listed co-ordinates refer to a trigpoint less than 1 mile from the final cache location. For this mystery cache you will need to visit three other caches. The first cache is GCHT3Z, “Chew Valley Station” and is a regular cache. Inside the cache container are the references for the two remaining caches. Both of these are multi caches, so you must obtain the actual co-ordinates of the final cache location: it is not sufficient to use the starting point for each!

Once you have all three co-ordinates you will need to complete the title challenge to obtain the intermediate cache location.

This intermediate location is in the car park of a local company: there is no actual container or logbook! You will need to note the three initial letters of the company name and the name of the street it is on. Translate the letters to numbers using the convention A=01, B=02 ... Z=26.

The final location can be found at N53 aa.bb3 W002 cc.dd9: this location has a little twist at the end. Initially you are looking for a 35mm film container, although ultimately the cache container is small sized at 470ml. You may also consider a trot up the hill to the trigpoint which references this challenge.

aa = 2nd letter of company + 3rd letter of street
bb = (4th letter of street * 3) - 2nd letter of street
cc = 1st letter of street
dd = 1st letter of company + 6th letter of street
