Ok, so every time I drive down to Pinns I see some scraggletoothed thing off on the hillsides. This is my attempt to document them in some fashion. The names are my own for lack of history.
There are 3 main areas that I can think of.
1. Limestone Plugs on Hwy 25, south of Hollister, north of the East side entrance. Grey in color. Bouldered one problem on the most accessible one, once upon a time ago in the 90s. Very sharp rock.
2. Tick Towers 1 and 2, on Hwy 152 on south side of highway. Tower 1 seems to be similar rock to Pinnacles, but possibly more munge encrusted. Appears to be on private property. Possible approach from West via clearings and oak forest. Tower 2, immediately next to hwy. Vastley smaller and more moderate. Maybe one clean line from my vague recollection upon looking at it.
3. "Rocks Road" sandstone cliffs on south side of hwy 101. Visible from hwy and mingled around hwy too. Largest formation approach may be best from East side via a dirt road.
Edit -
4. Sandstone clifflets off Hwy 25 south of Hollister, north of East side entrance to pinns. Take side road from where the reservoir and market are going east. When you see the clifflets, follow that dirt road across river bed. Clifflest will be on your left at that point. (not sure of names)
5. Coastal Crags - cf. mountaintools.com website local beta page for info.
