Surficial geology, Sandy Creek, British Columbia / [by] D.H. Huntley. : M183-1/121-2013E-PDF

"Canadian Geoscience Map 121 depicts the surficial geology over some 790 km2 covered by the Sandy Creek map sheet (NTS 94-O/13) in northeastern British Columbia. The map area lies at the western limit of the Liard Plateau and is incised by the Liard River and its tributaries. Bedrock is mantled by unconsolidated earth materials dating to the Late Pleistocene (Late Wisconsinan Glaciation, > 25 ka to ca. 10 ka) and non-glacial Holocene (ca. 10 ka to present). Deposits of till, green on the map, are generally suitable for placement of infrastructure. Glaciofluvial deposits with mineral, aggregate, and groundwater potential are coloured orange. Slopes disturbed by landslides, debris flows, and rock falls appear brown and pink. Glaciolacustrine and organic deposits with sporadically discontinuous permafrost are coloured purple and grey. Alluvial deposits prone to flooding, erosion, and sedimentation appear yellow on the map"--Abstract.
