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!
My big Agnes three person ultralight tent. It’s big enough for me, wife, and two dogs to sleep in comfortably. Two doors for ease of access and does well in windy and wet weather. Light enough to carry by myself and the poles are easy to repair. Had a tear in the rainfly a couple years back and they fixed it for a fair price. Excellent tent
