Conversion Tools Outage

    Our Conversion Tools will be unavailable due to a scheduled GIS services outage from Thursday May 6th to Monday May 10th.

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, which is 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.
