Meanwhile, back at the Ranch, catching up on Yosemite captures:

And what a delight it was to spend time with a legend like Alice :-)

Ugh -- no kidding. Yesterday I just finished "rough edits" on 42 pictures (including some stitched panoramics) just from the day at Point Lobos. I'm going to need help deciding which ones to edit for prints ... :-(

All I can say about the cooking is Robert was able to entice a teenager into having a second helping of braised baby artichokes ... ;-)

Well, even a Bear can tell you the vertical marks are water stains... We can hope Slippy will chime in and tell us how metamorphic granite (I think that's what this is), or "Gneiss" (I think that's what it's become) exfoliates (I think that's what it's doing) and why...

Bear, I followed you all the way to "exfoliates" but my mind boggles at a rock formation giving itself a shave. (and yes, Bear, I'm being silly.)

"Exfoliation" literally means leaves falling off, and can refer to a variety of medical (and other) conditions involving the outermost layer (e.g. skin cells) flaking off.

One of the chief ways this occurs in rocks is that water seeps into microscopic cracks, then in the Winter it freezes and expands, enlarging the opening. This process can repeat until the force of the expanding ice breaks the rock apart, or flakes off a piece if the crack runs parallel to and just below the surface.

A couple I don't think I'll be entering in any Free Study ...

All right! who needs a Slippy-geologist, when we have all this fine information coming in from people in the know.
Although if his arm became less colorful and ouchy, it would be fun to have his input.
In any event, these are rather spectacular patterns in age-old rock, captured nicely to show all that detail.

I actually took a (one) Geology class at UCSC, and actually (somehow) even passed ... let's see, I can remember taking Astronomy, Films of Fantasy and Imagination, Chemistry 1, Poetry (writing), Costume Design, Archery ... of course I actually "majored" in table-tennis, pocket billiards, and food service pre-management ;-)

Later on, I took community college classes in Press Operation and Repair, Process Camera and Pre-Press, Microbiology, Anatomy and Physiology, Physical Anthropology, English Comp, Tennis, Badminton, PageMaker ... and eventually made my way through the Primary Care Associate (Physician Assistant) Program at Stanford.

Heh, well, I can't really tell without being there... anybody willing to fly me down to take a look? ;-)

Because the bands don't seem to change direction with the surface, as water flowing over the surface would, I doubt it's from water in that way. Water seeping down vertical joints, maybe.

The first thought I had when I looked at it was small scale ophiolite.

Horizontal pressure on a still plastic intrusion could also encourage minerals to segregate into light & dark bands, the same idea as in gneiss. Minerals can even segregate that way horizontally in a layered intrusion, and later be tipped. I see some features are also oriented at two-to-eight o'clock... this makes me think of stress fractures related to horizontal pressure.

It could even be a piece of metasedimentary rock tipped up vertically during orogeny, but I think all the rock around there is supposed to be igneous.

I can't really tell anything without being there, or doing a decent job of Googling an answer, but I'd be interested to know if someone can find the answer.

ETA:...

I did find this in an article... "...dark water stains that stripe most of the Yosemite cliffs..."

Another article... Maybe metavolcanics tipped up?

This article is mostly about dome joints. In the Canadian shield I've seen plenty of horizontal joints caused by glacial unloading. The article mentions vertical stripes on the gentle slopes due to weathering on lichen, but doesn't mention the vertical faces. I'm getting the feeling Bear's water staining is the answer.

This is terrific,

And on top of that, you are all making me look up a bunch of new words. Always a plus.

Looks strikingly similar to "desert varnish", which is a manganese compound that gets deposited on rocks in dry environments.. Could be a similar process going on here, with water acting as the medium that dissolves and deposits the "varnish"..

Of course, I also immediately thought metaseds that were severely tipped... But that's what all geologists think immediately when they see a series of parallel lines in a non-sed rock.. :)

After examining it carefully though, I too have got to go with some sort of deposit from water... The lines actually aren't right for a metased..

Being mostly a Canadian Shield and Basin geologist, I bow to your desert experience. :-)

HaHaHa...
And on that note, moving from Yosemite to Big Sur, here are a few mementos of our journey down some of Highway One a couple of days ago. Landslides have been happening all up and down the coast recently, and even now part of the scenic highway is closed to any traffic. This section is open one lane at a time. Here's a brief picture story:

All this was worth it to go out and play with

Meanwhile, back at the Ranch, we're processing Monterey Bay Aquarium shots, so I thought I'd share a Sea Dragon with y'all (and a Grouper, added a little later...) â��

Looks to me as if you're getting there,

Melethia.

Bear also demonstrated his cooking talents -

which need no post-processing to
make the platter look good.
Roast new potatoes, grilled zucchini and a succulent roast of lamb. Yum.
