Interpretation of divide mobility, based on χ within individual catchments. Colour shading indicates average χ from channels (Fig. 2) in the local catchment area. The weight of the red line marking divides scales with the magnitude of Δχ between catchments. Black arrows indicate the inferred migration directions of the divides in order to reach geometric equilibrium (the length of the arrow does not indicate a rate). White contour lines show thermochronometric exhumation rates in mm per year for the last 2 Ma taken from Fox et al. (2015) and serve as a proxy for recent erosion rate
