Those are some fun stripes and you made them stand out well. Where is this? I am curious about the origins of this exposed stratigraphy.
Neat stripes and colors. I like the contrast between layers and the nice straight lines.
That is really interesting terrain. Like Alan, I am curious about where and what caused this.
Okay Tim.... you blew my mind with this one.... Rock with stripes at first glance seems like a 2 or 3 foot long rock. But then I see how tiny the massive pine trees are and I realize that they can't be miniature pine trees. Or can they? My mind and eyes are so confused as to the scale.... which is kind of good, its fun to have ones like this that can keep a person guessing.

Very nice. I'm also curious as to where. High desert CA?

Thanks everyone! It's west of Bishop, though I have no idea about the geology of the area. I was kinda hoping @Douglas Sherman would weigh in

Interesting - I thought all the rock west of Bishop was granite. Hopefully Douglas will chime in.

I just saw this one a little bit ago, Tim. It is hard to say without seeing the whole outcrop area. I can't tell what the rocks are for sure. Do you have any guesses? It kind of looks like the light layers are marble or hornfels but at this distance I can't tell what the reddish-brown rocks are. This looks metamorphic to me. It might be sills of lava sandwiched in between the whitish rocks and then metamorphosed. The other idea I have is that these layers were sedimentary and altered chemically by contact l metamorphism. If I was there, I could identify the rocks and would be able to tell what was going on.
Either way this is a really nice image, Tim. I am going to do some research in the literature and see if I can find something about this area?

@Douglas Sherman Sorry, I just left this hanging here... The rock I have identified for sure is shale and granite, though I have no formal geology. Only a science background and hanging out with other science-minded folk who occasionally talk about their geology background. Here are two more images of close ups of similar structures that I was able to get close a close up view. I'll send you the location in a message.
