I’m not a geologist, but I grew up in Ephraim and am very familiar with the areas you’ve explored here. (As a HS student I worked for the Snow College Cafeteria, and fed MANY groups of geologist from Ohio State…)

The strata area on Gal Hill is locally known as “The Cliffs”. We found it a great place to go and look for those chert nodules… the locals called “Cat Eyes”. I have a rock saw and found many of them to be very beautiful. They polish well and can be made into belt-buckles, or other types of jewlery.

I noticed you went to Dry Canyon (west mountains from Ephraim), but have you ever explored Maple Canyon?? It’s north of Ephraim, and NW of Wales. Completely different formations over there.

Enjoy!

The structure appears to be a “boudin” resulting from layer parallel extension with the void created filled by late quartz with a bed normal orientation in the ac plane (least compressive stress). If folding is involved then the fold hinge is in that plane and parallel to So (Bedding to you guys).
Of course I may be wrong but this is the least complex explanation

How in the world did that last structure form? It is as if the strata collided into each other!

The scenery is so gorgeous and crystalline — a wondrous place to work.
