| Abstract | The Bootjack Mountain region is bounded by the Quesnel and Cariboo river valleys to the north, Beaver Valley to the west and Quesnel Lake to the east. Till, of the Late Wisconsinan Fraser Glaciation, is
the dominant surficial material, mapped primarily as blankets but also as streamlined, hummocky and ridged topography. Glaciofluvial sediments, marking glacial retreat, are mapped predominantly as outwash terraces, as well as kame terrace and
ice-contact deposits interpreted to reflect ice-stagnation. Glaciolacustrine sediment veneers and blankets are mapped along Beaver Valley. Holocene colluvial and alluvial sediments are mapped in Beaver Valley and the Quesnel and Cariboo river
valleys. Colluvium is mapped as blankets, veneers, aprons, landslide and hummocky deposits whereas alluvial deposits include terraces, plains, and fans. Meltwater channels are generally oriented parallel to ice flow (northwest-southeast). Two
distinct ice-flow movements have been recorded in this region. An earlier west-southwestward flow (255°-275°) followed by a later, northwestward flow (293°-330°). |
| Summary | (Plain Language Summary, not published)
This map presents the surficial geology of the Mount Polley Mine region, in other words it presents the distribution of unconsolidated sediments and the
type of landforms in the mine region. This information is valuable for a variety of geotechnical applications (e.g. where is there a potential for landslide) and for the search of granular resources for infrastructure development and
maintenance. |
