Surficial geology, Bootjack Mountain area, British Columbia, parts of NTS 93-A/5, NTS 93-A/6, NTS 93-A/11and NTS 93-A/12 .: M183-1/209-2015E-PDF
"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. Glaciofluvialsediments, 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°)"--Abstract.
