The Mineralogy of Michigan, by E. W. Heinrich, Second Edition, extensively updated and rewritten by George W. Robinson, Michigan Technological University, Houghton, Michigan. This second edition of incorporates hundreds of color photos by Jeff Scovill, Dan Behnke, and others. The diversity and wealth of Michigan's mineral heritage has been reported and utilized since even before the first European settlers set foot in this area. Some of Michigan's earliest inhabitants had been using easily accessible native Copper for ornaments and weapons, and left their mark on Michigan's ancient history as the state's earliest miners. Their Copper artifacts reached all corners of the continent through existing trade channels. The exploration of the Lake Superior region in 1831 and 1832 eventually led to one of the biggest and most important "mining booms" in this country's early mining history.This second edition benefits greatly from both technological advancements in the science of mineralogy, as well as an increased awareness among amateur mineralogists, resulting in the discovery of many new minerals and mineral occurrences within the state.
