In 1962 Wilford had served as Editor of the first volume of “Contributions to the Geology of South Texas.” The book proved to be so valuable to Gulf Coast workers that it quickly went through two printings. By 1967 with the STGS as host, Wilford served as president of the GCAGS for its annual convention which was held that year in San Antonio.
