There have been various attempts at defining the subset of surfaces that compose the paleic surface in southern Norway. Geomorphologist Karna Lidmar-Bergström and co-workers recognize five widespread stepped surfaces. However, not all steps can be fitted into the five-step scheme, perhaps due to local doming. On eastern Norway some of the stepped surfaces merge into a single surface. In south-western Norway the Paleic surface is strongly dissected by valleys and fjords. Dovre and Jotunheimen are residual mountains rising from the highest of the stepped surfaces. These mountains define a former envelope surface that is warped. Possibly the warping of the envelope surface reflects doming of the crust associated with the uplift of the Scandinavian Mountains in the Cenozoic. The Paleic surface has been reconstructed over the fjord area of western Norway. In the reconstructed paleic surface, very gentle valleys follow the same course as Sognefjord, Hardangerfjord, Gudbrandsdalen and Østerdalen, but not of other valleys and fjords of western Norway.
