Surficial geology, Trail Lake, British Columbia / [by] D.H. Huntley ... [et al.]. : M183-1/123-2013E-PDF
"Canadian Geoscience Map 123 depicts the surficial geology over some 790 km2 covered by the Trail Lake map sheet (NTS 94-O/09), in northeastern British Columbia. Here, the Etsho Plateau lies within the Petitot River watershed and is drained by east-flowing Gote Creek, and northward by Dilly and Yesshadle creeks. To the north of the plateau, the Stanislas Creek drains northeast into the Petitot River. 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 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.
