This book is quite 'heavy' by that I mean it is filled with an abundance of facts and history, as you would expect from the title. I found myself having to re-read many sections just to get the welsh pronunciations correct in my head. I found the footnotes to be excessive and intrusive which detracted from the reading flow. There are no pictures in this book. I feel a few pictures would help readers who have been on the mountain relate parts of the text visually to where they have been. All in all a very factual book but a rather tedious read.
