Friday fold: The University of Wisconsin rock garden

I’m at a workshop in Madison, Wisconsin, this week.

I took the lunch hour today and walked over to the geology department to check out their rock garden and geology museum.

I was pleased to find a Friday fold in the rock garden: a limestone with cherty nodules/layering that has been folded….

Bonus: some nice bookshelfing/boudinage of the chert:

…And here’s another boulder of the same lovely stuff.

And here is another little train of cherty parallelograms:

Cool!

There was also a chunk of what appears to be the same thing in the museum inside…

Happy Friday!
