Fold in red siltstone, upper New York state


I collected this rock in 1967 in an outcrop somewhere in upper New York state when I was en route from Ann Arbor, Michigan to New Brunswick, Canada, to start my dissertation research.   I like folds that can fit in the palm of my hand, and the way these folds mimic what is observed at large scale in mountain belts.

Age & Formation
From a Paleozoic redbed formation in upper New York State.
