While drafting the residual glacier topography for the Z2 profile (Figs. 5B and 13B), the curves were inadvertently inverted (e.g., highs were incorrectly shown as lows). No findings or conclusions are affected by the error. The correct residual topography is shown in the new Figures 5B and 13B below.
