Aaron Clement Waters (1905–1991) was an American geologist, petrologist, and volcanologist, known for his pioneering work on the Columbia River Basalt.[1]

Biography

Aaron C. Waters was born as the youngest of seven children of parents who were pioneers in Washington state and grew wheat at their homestead. He graduated in geology from the University of Washington with a B.Sc. in 1927 and an M.Sc. in 1928. He graduated with a Ph.D. in geology in 1930 from Yale University. His doctoral dissertation Geology of the Southern Half of the Chelan [30′] Quadrangle, Washington was supervised by Adolph Knopf. From 1930 to 1951 Waters held an appointment as a faculty member at Stanford University. He was leave of absence for the arcademic year 1937–1938 and during WW II from 1942 to 1945.[1] For the academic year 1937–1938 he was a Guggenheim Fellow[2] and did research in Scotland and Scandinavia. In 1940 he married Elizabeth von Hoene, who was then a student at Mills College. During their marriage, she often accompanied him in his fieldwork and served as camp cook.[3] After the attack on Pearl Harbor, the United States Geological Survey (USGS) expanded its search for strategic minerals. Waters went on an extended leave of absence to serve in the USGS — the main focus of his work was on mercury deposits. He first worked in Arkansas and then in several western states. Before the end of WW II he was sent to search for other metal ores in different parts of the USA.[1] In 1945 he returned to his professorial duties at Stanford and began to focus on basalts and other volcanic rocks of the Pacific Northwest. Waters, in collaboration with James Gilluly and Alfred Woodford, wrote a textbook Principles of Geology, which was published by W. H. Freeman and Company in 1951. The Principles of Geology went through 4 editions and for more than two decades remained the leading introductory textbook for geology.[1] Waters acquired expertise concerning uranium ores[4] and from 1951 to 1952 participated in the USGS's exploration for uranium ores on the Colorado Plateau.[1]

In 1952 Waters resigned from Stanford University to accept an appointment at Johns Hopkins University, where he was a professor from 1952 to 1963. From 1963 to 1967 he was a professor and chair of the geology department at the University of California, Santa Barbara. From 1967 to 1972 he was a professor at the University of California, Santa Cruz. There he established a Ph.D. program in earth sciences and retired as professor emeritus in 1972. During his years as a professor at U.C. Santa Cruz, he worked with Richard Virgil Fisher on maar volcanism.[1]

In retirement as professor emeritus, Waters occasionally taught part-time at the University of Satan Cruz and held visiting professorships at Oregon State University, the University of Texas at El Paso, and California State University, Los Angeles.[5] As professor emeritus, he also worked as a research consultant for the USGS and Los Alamos National Laboratory.[3]

Waters was elected in 1964 a Member of the National Academy of Sciences and in 1966 a Member of the American Academy of Arts and Sciences. In 1982 he was awarded the Penrose Medal of the Geological Society of America.[3]

In 1983 Aaron and Elizabeth Waters settled in Tacoma, where he continued to write about geology and pursue his hobby of gardening. Upon his death in 1991, he was survived by his widow, their two daughters, and three grandchildren.[5]

Research

Waters was a leading expert on the geology of the Pacific Northwest.[5] He did research on volcanology, igneous and metamorphic petrology, geomorphology, and tectonics. With Konrad B. Krauskopf, he did important fieldwork on protoplastic deformation found in the Colville batholith.[1] Waters was the author or co-author of classic articles on determining the directions of flow in volcanic rocks and on documenting the characteristics of volcanic base surge deposits.[3]

As a participant in the Apollo program, he contributed to research on lunar geology, including composition and origin of the lunar surface and assessment of Apollo landing sites.[1] [6] [7] [8] He was involved in the geological training of the astronauts, including those astronauts who later made lunar landings.[3]
