This cache is not at the posted coordinates.
This multi cache highlights two plaques on the Rock Spring Trail honoring people who helped make Mount Tamalpais the park we enjoy today. I won't say anything about them in this write up as I want you to visit the two virtual stages to calculate the coordinates, but you might want to look them up when you get home to understand their contributions.
For the letter to number substitution: A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9, J=0, K=1..., etc.
Calculate North from the plaque at stage 1 (posted coordinates). If the plaque you found doesn't have enough lines, look for another plaque about 30 feet to your left. N 37 55.abc where:
- a = 5th line, 2nd letter
- b = 6th line, 3rd letter
- c = 4th line, 3rd letter
Calculate West from the plaque at stage 2. W 122 36.def where:
- d = 2nd line, 1st letter
- e = 3rd line, 2nd letter
- f = 3rd line, 1st letter
The cache is a preform tucked under a rock at the base of a tree right by the trail, downhill side. No need to move the rock unless the cacher before you changed things up!
