The pink Baraboo quartzite here encompasses phyllites with inclined slaty cleavage formed from compressional stresses in the PreCambrian (inclined to the quartzite).  The 1,630 million year old quartzites appear to contain crossbedding from the depositional environment the sandstone turned quartzite by metarmorphism.    The quartzite and phyllite are vertical layers that transition syncline-anticline folds (the syncline continues into the ground).  The cleavage was at right angles to the compressional forces that formed the folding (see diagrams in the reference to Callan).
