Biographical Sketch
Dr. Lee taught geology and remote sensing at the Colorado School of Mines for 37 years before his retirement in 2006. Courses included earth and environmental systems, physical geology, historical geology, field geology, hydrogeology, photogeology, and remote sensing. Research emphasized applications of remote sensing to exploration for mineral and water resources.
Research Interests
- Tunguska, the mysterious explosion that flattened millions of trees in Siberia in 1908, remains an unsolved mystery after 100 years.
- The Popigai impact created one of the largest and best-preserved impact craters in the world and instantaneously transformed large amounts of graphite into diamonds.
- The Missoula Flood, generally accepted as the largest flood on Earth, devastated large parts of four states on its rush to the Pacific Ocean.
- The Altai Flood in Siberia presents evidence of an even larger flood and suggests that such megafloods may not have been all that rare.
- Smaller outburst floods, like the Three Glaciers Flood on the Arkansas River in Colorado, were more numerous, but catastrophic nonetheless. Colorado also saw catastrophic outburst floods on four rivers in the San Juan Mountains.
