Please note:
The cache was moved 11/7/18 and a slight change made to the puzzle. If you solved before this date, just put the old solution into Certitude and it will tell you the correct solution.

The cache is located at N 38 0x.xxx W 122 3x.xxx
where the last four digits of north are = (DAC x BA) - (FF x GK) + 12
and the last four digits of west are = (CDH x EA) - (EE x AHJ) - 6

You can validate your puzzle solution with certitude.
