The book that I'm currently reading is called Denison's Ice Road. It is a book about a man named John Denison who was the first to construct a network of hodge podge ice roads throughout the Canadian wilderness to supply remote mines and villages. I just started the book, but have gained a real interest in it. The one question that I have about this book is " How could the ice support such a load like that." John said he wouldn't started driving on the ice until there was at least 18 in of ice. You would also need about 36 in of ice to support a hundred ton load.
