Rogers (1808-1866) was an American geologist educated at Glasgow. He was originally the director of the New Jersey Geological Survey before becoming director of the first Geological Survey of Pennsylvania where he undertook the first comprehensive geological survey of that state. Based on studies in the Appalachians with his brother William Rogers, he formulated a theory on mountain building which was presented to the first session of the Association of American Geologist and Naturalists in 1840.
In his address at the 1844 meeting of the association Rogers once again visits the dynamics of mountain building. He begins his talk with a review of the history of geological research in America and follows this with a description of the stratigraphy and strata found in eastern America. He finishes his address with a discussion of geological dynamics at work in mountain building.
