description: "David Dale Owen was a prominent American geologist who conducted the first geological surveys of Indiana, Kentucky, Arkansas, Wisconsin, Iowa and Minnesota. Owen served as the first state geologist for three states: Kentucky (1854–57), Arkansas (1857–59), and Indiana. His first geological work was as an assistant mapping the geology of Tennessee in 1836. In addition, Owen was appointed as a U.S. geologist in 1839 and led federal surveys of Iowa, Wisconsin, and northern Illinois (1839–40) and in the Upper Midwest (1847–1851). Owen's greatest legacy lies in the eleven volumes of published reports from his state and federal geological surveys, which increased the general knowledge and understanding of American geology, the structural geology and paleontology of the United States, and the mineral wealth of the Midwestern states. Owen's most significant contribution to the field of geology was identifying and naming major geological formations of the Mississippi River Valley and placing them in relative position on a geological timeline. He also helped to standardize the nomenclature of geological structures in the Midwest."
