Geocache Description:


This geocache is the final cache of a 5-part “Mountaintops of Marin” cache series that has been placed on some of the highest mountaintops, hills, and ridgelines of Marin. The challenge of the series is not the hide but getting there, though all of the caches are accessible by well-maintained fire roads and/or trails.

Here are links to the other caches in the series:

Mountaintops of Marin #1 - Mount Burdell, GCZCGW
Mountaintops of Marin #2 - White Hill, GCZCH0
Mountaintops of Marin #3 - Pine Mountain, GCZCH5
Mountaintops of Marin #4 - Barnabe Mountain, GCZCJ0

The cache is not located at the above-listed coordinates. In order to find this cache, you will need to find the four other caches in the series to obtain clues necessary to solve the final coordinates, as follows:

North 3L AB.CDE
West 122 FG.HIJ

L = (G+E)+(D-F)+(C+A)-(J+B)-(H+I)+9
