This map visualizes the results of modelling the sub-Cretaceous unconformity surface in the Slave Lake – Peace River region of Alberta. The map shows the elevation of the unconformity in the subsurface, delineates the boundaries of stratigraphic units sub-cropping at the unconformity surface and provides a detailed reconstruction of the paleotopography. This reconstruction represents what the surface looked like prior to the deposition of Lower Mannville and equivalent strata, including highlands and drainage pathways. These results are an integral part of a larger project at the Alberta Geological Survey to create a provincial-scale 3D geological framework model of Alberta’s subsurface.
