Editors' note: This essay by Dan Arreola begins the second set of retrospective pieces commissioned to celebrate the centennial volume. Members of the Editorial Board responded to our request to prepare brief commentaries on landmark Geographical Review articles that were influential in their professional careers. Although many other articles touched the minds of emerging scholars, this small sampling covers a fairly wide swath of the fabric of American geography. It also reminds us that each future article has the potential to have a similar enduring value and help open new intellectual vistas. In addition to Arrreola's piece, the short essays include the musings of Barry Keim, Susan Walcott, Larry Ford, and Risa Palm.
