Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Ralph J. Roberts (1911–2007) was an American geologist and research scientist with the USGS. He is credited with the discovery of the Carlin and Battle Mountain Gold Belts, which make up the richest gold-mining region in Nevada as well as the United States. Roberts grew up in eastern Washington, and earned his bachelor's and master's degrees from the University of Washington in Seattle. His PhD research, which he conducted at Yale University, defined the Antler orogeny, a major mountain-building episode in the late Paleozoic.
