Driving south from Wick to Inverness - my son now driving. Admittedly, most of the pics look like the second one.

The road that passes by our place - with more & more traffic every day...

The road that passes my place - not much traffic today. And not a single palm tree in sight.

Interesting in what appears to be a large kink fold in those meta sediments.

I think those are upper/late Proterozoic to lower/early Paleozoic = late Pre-Cambrian to Cambrian sediments first disturbed in the Ordovician (Taconic) and mashed more later..

No signs here, but I'm pretty sure that this is the same fold in your first image, as we also pulled off the road here (previously posted elsewhere):

Agree 100%. That is the same distorted layering at the upper right of the rocky outcrop in the photo I posted. It's a grand example how something brittle can distort plastically when confined under extremely high pressure. Students have trouble wrapping their minds around how ice in a glacier - normally perceived as brittle - is actually flowing in a plastic manner, how the ice can flow over and around a firmly anchored rock outcrop, how the center top of the ice can be moving faster than the margins or the base. I used to attempt a mental understanding by explaining how a copper tube bent around your knee causes a "kink" versus slipping a confining spring around the copper tube and getting a nice rounded bend, but too few students were familiar with or could imagine that spring device.


BTW: Ever since I first heard it as an undergrad, I have loved the term "disturbed strata." In truth, the term can be applied to the vast majority of Earthly rocks.

Those quartzites appear regularly interspersed thoughout the upper vertical section similar to cyclothems, indicative of transgressive/regressive seas during the late Proterozoic.

A good example of the power of glacial carving can be shown throughout the islands east of Portland, ME, that show the direction of glacial movement in the islands linear shapes.

On a few occasions I took students to the top of Mt. Holyoke, one of the highest points nearby and easily accessible with a 15 passenger van up the paved road. There are deep glacial grooves in the exposed bedrock, about 700~800 feet above the general terrain. "What made these grooves?" I would ask. Inevitable answer "Running water." "Where," I would counter, "is the watershed that could supply such a massive discharge?" Bewilderment. Then I tried to get them to image ice extending another 1,000 feet or more above where we standing, and the pressure ("weight") such a mass would exert on a bus-size boulder that the ice was dragging across the top of the mountain. At least a few could grasp the magnitude, but it was very difficult for most of them.

The power of all that weight and force is awesome! It is always fascinating to me to see signs of glaciers as I hail from the unglacier-touched south US
