Figure 4.

A. Modern Alaska topography (m) at 10 km resolution sampled from 30 m SRTM DEM. Black contour represents modern coast, red box represents the area used in the numerical model.

B. Model geometry with topography (m) at 10 km horizontal resolution. Z-axis is vertically exaggerated 10X. The upper crust is defined by a pressure dependent Mohr-Coulomb model (light brown), the lower crust is defined by a temperature dependent Drucker-Prager model (dark brown), and the mantle is defined by an Elastic model (red).
