This dataset was created for researchers at Hakai to utilize in instances where data on subsurface material type and relative age would be beneficial. It was created with a goal similar to other surficial geology maps in the region (e.g. http://www.env.gov.bc.ca/van-island/maps/surfical.jpg), with a focus on unconsolidated sediments deposited and reworked since the last glaciation.

Data used in the generation of this map was collected through several different means. In areas with the highest resolution (e.g. proximal to the institute), subsurface data was directly observed through soil pits, natural sedimentary exposures, or cores. Where this was not possible, visual interpretation of a bare earth model generated from airborne lidar data assisted in extrapolation of geologic and landform trends that were directly observed. Derivatives of this model were also used, such as principal component analysis of hillshade models (e.g. Devereux et al., 2008) and a ruggedness index (Riley et al., 1999).

Map data were created by Jordan Eamer and Dan Shugar.

This shapefile contains oriented linear and areal features identified through analysis of the DEM. These data may be used in a future study of glacial ice character and directionality.
