Quicksilver Mining in the Terlingua Area was originally written by Kathryn B. Walker as the thesis to fulfill the requirements for her master's degree. Her advisor, Dr. Clifford B. Casey, encouraged her to publish it. But it wasn't until years after her death that her daughters were able to bring her dream of publication to fruition. This book is masterfully structured and meticulously researched. It takes the reader on a comprehensive ride explaining mining in Terlingua from a technical, geological, sociological, and economic perspective.
