This map is a rendering of a computer-generated geostatistical model of the thickness and distribution of sediment overlying bedrock in Alberta using a newly revised bedrock topography model of the province (see Alberta Geological Survey Map 551).
This map updates Alberta Geological Survey Map 227: an earlier reconstruction of the sediment isopach map of Alberta.
The incompleteness of this map reflects the absence of sufficient data to interpret part of northern Alberta.
