Rich Mountains of Lead-The metal Mining Industry of Cwm Rheidol and Ystumtuen by Ioan Lord, published by Vale of Rheidol Railway.
I have just bought copies of this book for myself and my Caving club and whilst I have not read it yet to provide a review, I can tell that on flicking through it, the book is an excellent addition to any caver’s library. It’s a bit expensive at £45 but gives 272 A4 pages of brief historical fact, modern exploration accounts, surveys and excellent photos of the metal mines around Cwm Rheidol and Ystumtuen in Mid Wales. I bought mine from Mike Moore and Vale of Rheidol Railway also sell them.
Ioan Lord is to be commended for writing and publishing this excellent book.
