Henry Darwin Rogers is a familiar figure in the history of American geology, especially as the director of the first state geological surveys of New Jersey and Pennsylvania. Although best remembered for the survey work, Rogers considered his theory of mountain elevation to be his most important scientific legacy. Based on studies of the Appalachian Mountains, Rogers's elevation theory was the first American explanation of the dynamics of elevation. As a study of the Pennsylvania survey, this volume offers new insight into the origin and problems associated with early surveys. As a study of Rogers's life and work, it presents a portrait of a man with strong convictions and dedication and examines the development and application of his ideas.
