Died 19 Feb 1949 at age 91 (born 31 May 1857).
U.S. geologist known for his structural and geomorphological analysis of the Appalachian Mountains and Mount Ranier. His interests were primarily in the broader aspects of physical and dynamic geology, in the formation and origin of rock structures. His work included studies of denudation (a form of erosion) chronology in North and South America and Africa, model experiments of folding and deformation, paleogeographic mapping of North America, and theories of the differentiation of the Earth's crust. He was interested in California geology, especially in faulting, seismology, and earthquake hazards. His concern over earthquakes led him to study the engineering hazards of the Golden Gate Bridge and to fight for a more stringent municipal building code.
