While at the Wyoming Geological Survey on the University of Wyoming campus (1977–2006), Hausel discovered dozens of colored gemstone, diamond and gold deposits and occurrences. As a consultant for WestGold, a crew of six geologists including Hausel discovered the Donlin Creek gold deposit in Alaska in 1988; now recognized as one of the larger gold deposits discovered in North America in the last 100 years. He was inducted into the National Rock Hound and Lapidary Hall of Fame in 2001 for contributions to geological sciences and also presented the Prospectors and Developers Association of Canada's 2009 Thayer Lindsley Award for discovery of a major international gold deposit. In addition to the Donlin Creek gold deposit he discovered the Rattlesnake Hills gold district in Wyoming in 1981 – a district with dozens of gold anomalies that is currently being explored and developed for both Kalgoorlie- and Cripple Creek-type gold deposits. He contributed to nearly one hundred books and 650 papers and maps on geological sciences and martial arts. Hausel is a diamond geology specialist and contributes to articles for the ICMJ Prospecting and Mining Journal. Books By Dan Hausel
