A guy named Jon Snow came to Telluride to talk about ice and fire.  No, not the Jon Snow from Game of Thrones, but rather Dr. Jonathan Snow, arctic explorer, professor and chair of geology and geophysics at Louisiana State University.  He says there’s all sorts of fascinating stuff going on with the undersea volcanoes deep beneath the Arctic ice.  Dr. Snow is joined by award-winning broadcast journalists Judy Muller and George Lewis.
