This article critically reflects on our effort to "teach across the divide", by integrating physical and human geography in a new first-year course. We achieved this integration by structuring our course around a series of key events, in order to draw out the interaction of "natural" and "social" forces. After setting out the intellectual and institutional reasons for integration, we illustrate our approach with reference to one of the key events covered in our course: Hurricane Katrina. Finally, we draw on our own reflections and student evaluations to consider the positive outcomes of our approach, and the challenges it poses. (Contains 3 notes.)
