5203 |a"Canadian Geoscience Map 126 depicts the surficial geology over some 790 km2 covered by the Tightfit Lake map sheet (NTS 94-O/10) in northeastern British Columbia. The map area lies at the western limit of the Etsho Plateau and northwest limit of the Fort Nelson Lowland. This boundary is a major drainage divide: Klenteh Creek and other tributaries to Kiwigana and Fort Nelson rivers drain the south-facing escarpment of the Etsho Plateau and Fort Nelson Lowland; to the north, the plateau and Tightfit Lake drain north into the Petitot River valley. Bedrock is mantled by unconsolidated earth materials that dates 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 and eolian deposits with mineral, aggregate, and groundwater potential are coloured orange and buff. 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.
