Well, there you have 'em, folks -- two very durable building materials.
Top photo is a barkless fallen oak out at China Camp.
And if you've ever been on Conzelman Road overlooking the Golden Gate Bridge -- then you've seen the amazing patterns of all those layered, bent, and folded orange-red rocks. The rock is called "Chirt".

Fascinating! I would never have guessed what they were.
