(1857–1949) Structural geology in the first half of the twentieth century was much advanced by the work of Bailey Willis, who in his later years made laboratory models of the major structural features found in the Appalachian mountains and the Rockies. After taking degrees in mining engineering and civil engineering and a spell as geologist for the North Pacific Railway, prospecting for coal in Washington State, Willis joined the US Geological Survey. His fieldwork was in the mountainous western States, where he studied the magnificently exposed tectonic and structural features. He produced some sixty publications for the Survey during this work on structural geology.
