In his carefully written text, geologist Paul Garvin has combined scientific facts about minerals with an appreciation of their history and beauty to produce a book that will appeal to scholars, collectors, and the general public. Garvin begins with a brief treatment of the origins of Iowa's minerals, moving from the oldest - with ages well in excess of a billion years - to those most recently formed. He describes the state's major mineral occurrences, providing detailed information for both specialists and amateurs, including how to obtain access to collecting sites. A history of Iowa's mineral industries complements Garvin's more technical information; this history is supplemented with stories about the Cardiff Giant (who now has his own web page), Ottumwa's Coal Palace, and the meteor falls of the late nineteenth century.
