      Thanks for your response, yes that is one of four theories. Geologists have not come to a singular conclusion as far as I know, however. So the four competing formation theories are that it was a laccolith, a volcanic neck or plug - and more recently that it could have been a volcano that came in contact with ground water (Maar theory), or a stock. If you have further research I would like to read it!
