Report Description

The map shows relative drift thickness in north-central BC, covering NTS mapsheets 93G, 93H/w and 93J/s. Constructed from previous mapping and recent field-checking, the map is intended as an aid to mineral exploration, providing information on the distribution and relative thickness of surficial sediments and generalized ice flow history. This will help to determine areas that are more suited for drift prospecting and bedrock prospecting, as well as provide guidance as to the dominant transport direction when interpreting the results of geochemical surveys.

The map in PDF format, the ESRI ArcGIS map document and data used to produce the map are included in this release. The datasets include ice flow indicators, drift thickness and outcrop locations, along with base map features providing background context.
