Formerly known as Salem Quartzite it is a South Jersey stone and possibly quite similar in adjacent states to the south. The report at the link below is a Doctoral Dissertation by South Jersey archeologist Alan Mounier. The name "Cuesta" was coined by Jack Cresson according to the report because of where the outcrops are found. I've met Jack quite a few times and spent time with him learning, beach combing, breaking rocks and just hanging out. A great person. Alan I've corresponded with in the past and he was most cordial. The material is a tool destroyer and I tried the techniques from the report: heat spall the small boulders and reheat for stages of reduction. I had some little luck with the material.
