Summary

A simple model with rotationally symmetric ice load and constant dynamic viscosity 1021 Pa s for the mantle is shown to give a reasonably accurate description of the Fennoscandian forebulge height (40–60 m). This value for the viscosity is adopted since it leads to a satisfactory value of the present uplift velocity in the centre (about 10 mm/y). Surface tilting, and shear stress are also calculated.
