A Mystery Photo for a Tuesday (and a bonus mystery photo)

Hi all! I've been away, and out of contact with the world for a few days. Is anything going on geologically? OK, yes, I did actually hear about the quake in Virginia, but not until many hours later...

Anyway, I was doing some field trip research in Southern California. Even though I grew up down that way, and worked at Santa Barbara City College for four years, I saw a lot of new and very interesting territory. Expect to see some new "Other California" posts over the next few weeks.

In the meantime, here is a mystery rock for you to identify. I can't give you too many clues, other than to say to trust your intuition, and realize that the answer will only be sort of half right
And here is a second handful of mystery samples to identify, from the same outcrop.

So, what are these rocks, and how did they form?
