Geology, Toad River (southeast), British Columbia / [Authors: M.E. McMechan].: M183-1/149-2013E-PDF
"The Toad River southeast map area (NTS 94-N/SE) in western Liard Basin is underlain by a thick Triassic to Cretaceous clastic rock-dominated succession. A prominent escarpment held up by resistant Upper Cretaceous sandstone and conglomerate of the Sikanni and Dunvegan formations marks the west limb of the Liard syncline. To the east, exposure is limited to more incised drainages, mainly of the Dunvegan Formation. A few discontinuous gentle folds occur. To the west the amount of deformation decreases noticeably northward. In the southwest, the Foothills are characterized by a well developed terrain of northwest-trending, open folds beautifully outlined by resistant Triassic sandstone of the Liard Formation. North of Liard River only a few gentle north or northwest-trending folds deform Triassic and Lower Cretaceous strata in the transition zone to the southern Liard Fold and Thrust Belt. Drilling has shown the prominent Toad River Anticlinorium overlies uplifted Proterozoic and Paleozoic strata"--Abstract.
