Geocache Description:

This is an OFFSET Challenge cache, so before you can log a find you have to solve a puzzle to get the final coordinates and must fulfill a certain Qualification.
Do not visit the cache page coordinates which are not an accessible location.

Well that is a good slogan for any challenge.
I wanted to create an escalator challenge that gave more folk a chance to seek the cache and do so very easily in the early stages but that was crushed by the guidelines and reviewer.

So the double devil was born.

You need to find caches on their anniversary of placement.

Why the double devil?

You are aiming for one 9th of a year on anniversary dates.

366/9 = 40.666666

Some accredit rightly or wrongly the number 666 with the devil.

So you need round up and fill the calendar grid with 41 days where you have found caches on anniversary days.
Simple rules;

1) Only caches listed on
2) All previous finds count.
3) Proof of  finds with hyper link to cache pages must be provided in your log or by other means.
4) Proof of finds must include both found date and placed dates and should be sorted in month and then day order.

I would not expect anyone to do more than I have myself and my list of qualifying caches can be viewed here.


Solve this riddle to get a five letter word   ( also an answer related to

The center of the route to a pot of gold.  
0 0 0 0 0

Convert that word from the lowest base that will accept the letters into an eight digit decimal value.

0 0 0 0 0 0 0 0

Evaluate the formula to find the true cache location.

N51 25.(F+H) (H+B) (G-D)   W001 09.(E+H) (F+A) (D-A)

Good luck with your challenge.
