"The La Biche River map area (NTS 95-C), Yukon and Northwest Territories occupies the Liard Plateau and the southern termination of the Franklin Mountains. It is situated between the northern Rocky Mountains to the south and the Mackenzie Mountains to the north. The area is thickly vegetated and varies from hilly in the western portion to mountainous in the east. Bedrock exposures are sparse and concentrated along streams, with a few open ridge tops in the west half and with better exposure along open ridge tops of the Beavercrow, La Biche, Kotaneelee, and Liard ranges of the east half. The area is underlain by Proterozoic to Late Cretaceous sedimentary strata, along with Neoproterozoic and Eocene intrusions. Folds and faults preserved in the area were generated during two deformational events, a Neoproterozoic event and a Late Cretaceous to Eocene Laramide deformation. Within the Kotaneelee gas field, gas has been produced from a Devonian carbonate reservoir beneath the Mount Martin anticline"--Abstract.
