AbstractDetailed 1:50 000-scale Quaternary mapping and reconnaissance-scale till geochemistry and kimberlite indicator mineral surveys were carried out within three NTS 1:250 000-scale map areas: Laughland Lake (56 K), the northern half of Walker Lake (56 J), and the southern half of Arrowsmith River (56-O). Quaternary mapping included characterization of surficial geology units, identification of glaciogenic landforms, and the measurement of ice-movement indicators. New data related to the last active ice to occupy areas in NTS 56 K, 56 J, and 56-O suggest divergent ice movement originating from a southward-opening, arcuate ice divide or an ice-centres saddle scenario. Further investigations will elucidate the complex ice-movement history and test new hypotheses regarding the genesis of some glacial landforms and sediments.
