Ice-Flow Indicator Compilation, British Columbia 

 

BCGS Open File 2013-06

 

December 12, 2013 update


by Travis Ferbey, Holly Arnold, and Adrian S. Hickin

 

This compilation consists of over 119,000 ice-flow indicators digitally captured from published and unpublished surficial geology, terrain, glacial features, and bedrock geology maps in British Columbia. Ice-flow indicators include outcrop-scale features such as striations and grooves and landform-scale features such as drumlins and flutes. These data illustrate ice-flow directions for the Cordilleran ice sheet during the Late Pleistocene.  This compilation will be of interest to those seeking to understand ice-flow histories, a critical parameter for interpreting geochemical and mineralogical data from glacially transported sediments typically collected in drift prospecting surveys.  These data will also benefit researchers who are more generally interested in landscape interactions of the Cordilleran ice sheet during the Late Pleistocene and the locations and evolution of ice divides.

 

In this update, 296 features have been added to the compilation and a shapefile has been added to the datafile.
