What caused this rock formation?

Am a masters student with a focus in structural, to answer this, yes they can. An old professor of mine described structural geology as “fractal”; meaning large scale tectonic structures typically are represented in small scale versions (imagine a Russian nesting doll). A huge part of geologic mapping, especially in regards to structure, is mapping “micro” structures. In metamorphic rock especially you can look at shear zones, micro folds, etc. to gain an idea of the larger scale stresses and forces. In this case, it could be a localized stress, but my first guess would be it’s representative of the greater movement, but it also kind of depends where you’re at. If you’re in the east coast, I’m guessing this is somewhere west of the appalachians?
