Figure 2. A north-south transect through the San Bernardino Mountains (extents shown in Fig. 1) giving mean denudation rates for the plateau, its northern and southern margins, and one of the steep southern ridges. Denudation rates (in mm/ka) derived over million year timescales using incision and thermochronology techniques are shown in red; rates measured over millennial timescales by cosmogenic nuclide analysis are shown in blue. Dashed grey lines indicate major faults. Rates in the south are similar over different timescales; rates on the plateau and its southern margin are vary over different timescales (modified from Binnie et al., 2008).
