Bedrock Topography of Alberta, Canada

This map is a rendering of a computer-generated geostatistical model of the bedrock topography of Alberta using previously published information from Alberta Geological Survey maps and reports, as well as new data. This map updates Alberta Geological Survey Map 550.

The bedrock topography of Alberta is the surface of the top of Upper Cretaceous and Paleogene bedrock, and reveals geomorphic features created by Paleogene to Recent river systems and Quaternary glaciation.

Explanatory notes, references, and data sources appear on a supplementary page to accompany the map. These notes describe the distribution of physiographic terrain elements of the bedrock surface across Alberta, and the data sources and geostatistical methods used to interpolate this surface.
