In the September issue of GSA Today, Paul Bierman of the University of Vermont–Burlington and colleagues present a cosmogenic view of erosion, relief generation, and the age of faulting in southernmost Africa. By measuring beryllium-10 (10Be) in river sediment samples, they show that south-central South Africa is eroding at the slow rate of about five meters per million years, consistent with rates in other non-tectonically active regions.
