Geology, Mount Prudence, British Columbia / [by] M.E. McMechan. : M183-1/169-2013E-PDF

"The Mount Prudence area (NTS 94-N/05) in the western Liard Basin is underlain by Middle Proterozoic to Triassic strata. Poorly exposed Triassic siltstone and shale form the dominant level of exposure. Folds dominate the structural style. These probably formed in the latest Cretaceous and are well exposed along Liard River and where outlined by more resistant units. Two significant faults (Sulphur Creek and Forcier) carry Middle Devonian and older strata to the surface. A regionally significant change in the orientation of structures from northwest in the Rocky Mountain Foothills to north or northeast in the Mackenzie Mountains and Liard fold and thrust belt occurs in the northern part of the area. This map incorporates extensive observations from a major unpublished geological study of the Liard River corridor prepared for B.C. Hydro in 1984 as well as new data collected during fieldwork as part of the Geo-mapping for Energy and Minerals (GEM) project"--Abstract.
