Per Diego Concha: I called the DCR today and spoke to a ranger who said they no longer allow climbing at Rattlesnake Rocks because of endangered species that live near the crag and are sending climbers to Quincy Quarries nearby.
Description
This is more of a highball, seeing as the crux is right off the ground (talus!). After the traverse crux and a big reach, sinker buckets get you to the top.
Location
On the leftmost face, start off a large undercling and goes to a left-angling traverse up into the shallow dihedral.
