Happy 12th Birthday Geocaching - The Baker's Dozen Mystery Cache

THIS CACHE IS NOT LOCATED AT THE SPECIFIED COORDINATES!!!

YOU DO NOT NEED TO VENTURE INTO THE WOODS (WHICH ARE PRIVATE PROPERTY) AT ANY TIME.

This cache is the culmination of the Dozen Dashes for 12 years of caches series published between 21 April and 2nd May 2012.

Over the last 12 days 12 cache and dash caches have been published each with part of the location of this cache.

You will need to set aside at least an hour for this, maybe more.

PLEASE NOTE: The last location of the final (the middle tree) is now a host to nesting snowey owls. The final has been relocated about 100 yards south east. The information that points you to the middle tree has been faintley replaced with new hint ad coords but you'll have to look close as I dropped my pen a mile away on te walk to the cache and had to scrape it into the paper with my car keys! It will soon be replaced with the correct info.

If you have completed all 12 previous caches then you have all the information you need to START this cache quest.

Now it's time to get to it.

The equation you need to plug your answers into is:

Congratulations to JLAM for the FTF :)
