Digital Geotechnical Database for the Mackenzie Valley/Delta Region, Version 1

The Mackenzie Valley Geotechnical Database is a compilation of existing geological and geotechnical data for over 12,000 boreholes that extend from the arctic coast to northwestern Alberta. Additional information on site conditions such as terrain disturbance, vegetation and geomorphology are also included. The original database, compiled in the early 1970s by Proudfoot and Lawrence (1976), contained over 11,000 boreholes. Most of these data were obtained from pipeline and highway related field drilling programs conducted between 1970 and 1975. In the early 1990s approximately 1400 boreholes were added to the database. These data included some of the site investigations undertaken for the construction of the Norman Wells Pipeline Project and the Mackenzie Highway. The Geological Survey of Canada has compiled data for all boreholes into a searchable GIS compatible relational database in Microsoft Access format.
