Welcome to the top of Wolf Ridge/Hill 88 at 950', it is listed as Peak 75 of the Nifty Ninety peaks of the Bay Area. I was turned on to this list by Penguinphloppers after going after one of his new caches called Nifty 63 - Point Reyes Multi. He has also created a couple of challenges for bagging peaks. The first one is GC9X22Y - Nifty 90 Encouragement Cache Tier 1: 25 and the second one is GCA1RW1 - Nifty 90 Encouragement Cache Tier 2: 40. I love hiking to the top of mountains so I was quite interested in the list and challenges. There is also another list that you can find on "Peakery". It is a 100 peak challenge for the Bay Area.
Wolf Ridge/Hill 88 is within the GGNRA, so no physical caches are allowed within that territory. So this is done as a multi, with the final container outside of GGNRA. You will hike to the top of Wolf Ridge and gather the information needed to solve for the final location. It is a gorgeous hike with outstanding views. Visit the six stages on top of Wolf Ridge where you will find all the necessary information to get the final coordinates. The final container is not withing the GGNRA. This hike is designed to be done from the Tennessee Valley Parking Lot. If you start anywhere else you may need to make a much longer drive to get your name in the log.
Dogs are welcome on certain trails. To the best of my knowledge, they are not allowed at the Tennessee Valley TH. If you want your furry friend to join you please download the Marin Headlands map so you can see where dogs are allowed. https://www.nps.gov/goga/planyourvisit/upload/map-mahe-4c-2022-01-22_web.pdf
The final is located at N37 52.ABC W 122 31.DEF
A: What is the numerical value of the 5th letter in the red portion of the sign. (A= the numerical value -2)
B: You are standing in the middle of two concrete structures. How many platforms combined are on top of both of the columns. (B= Number of platforms -4)
C: How many electrical pipes are coming out of the ground? (C= Number of electrical pipes +2)
D: on the concrete slab how many dual pipes are there in the ground. Example: if there was one dual pipe it would count as two. Do not cut the individual pipes that are by themselves.
E: How many electrical panels are there? (E= number of electrical panels + 2)
F: There is one big yellow letter in the center of the concrete pad that belongs here. What is it? There may be an extra letter but it does not belong here. Ignore that one. What is the Numerical value of the correct letter? (F= numerical value of the letter -1)
