a, A simple SIA model reproduces the general pattern of modern glaciation on the modern topography. b, The same model parameters produce a very different pattern of glaciation on the pre-glacial topography. Importantly, it appears that the pre-glacial landscape can support more ice south of approximately 66° S but less ice to the north of this location, for a simplified modern climate. This highlights how uplift and erosion control the amount of ice topography can support. The SHALDRIL site is just to the northeast of our study area.
