Darrel S. Cowan, Secretary

Darrel S. CowanDarrel S. Cowan was born and grew up in Los Angeles and is sure that his love for all things desert germinated on the weekend trips with his family to Death Valley and Joshua Tree, and all over the Mojave to look for geodes. He received his BS and PhD in geology from Stanford University and spent his first professional career as an exploration geologist in Shell Oil Company from 1971 to 1974. He accepted a faculty position in the University of Washington, where he is currently a Professor Emeritus in the Department of Earth & Space Sciences. He is a field geologist, having studied rocks in mountain belts worldwide to reconstruct geological history. Although he had visited the Death Valley region as a kid and college student several times, he began serious research there in the early 1990’s. Death Valley itself is a world-class example of how Earth’s crust is being actively stretched or extended. Normal faults are responsible, and our current project involves looking for small earthquakes that would be evidence for active normal faulting. He still brings his senior-level classes to the region, including the Amargosa Basin, to study the exemplary geologic record extending from about 1.7 billion years ago to the present day.
