Geology in Iowa, early history; Silurian System; Calvin, Samuel; Hall, James; Owen, David D.; White, Charles A. ; Wilson, Andrew G
The development of geology as a scientific discipline in Iowa had an early and active history dating from pre-statehood. A high standard of geological observation mixed with pioneer ruggedness evolved from the first reconnaissance work of David Dale Owen in 1839 to the detailed, county survey work of Samuel Calvin at the turn of the century. Aspects of explorations made within this period are highlighted, particularly those with reference to the Silurian System. Strenuous journeys, rival personalities, and the influence of scientific controversy in Europe characterize the early geological explorations in Iowa.
