Combining research and wonder, this collection of poems is devoted exclusively to geology and mining. Quite literally, it goes underground. From volcanoes to vitamins, the book presents a wealth of factual information, including a helpful glossary. As well as past, more fanciful notions about how rocks, metals, and minerals fit into our human picture, it explores the history and technology of mining, and its social and economic impact. In its pages, knowledge and imagination meet, to both inform and delight.
