This paper presents an overview of the field research conducted during the 2001 season, along with preliminary field observations, from the second year of the Committee Bay Project's Quaternary studies. The objectives of these studies are to compile high-resolution terrain inventories for the Laughland Lake, Walker Lake, Arrowsmith River, and Ellice Hills map areas of central Nunavut; to begin a reconnaissance-scale drift prospecting program that utilizes both heavy-mineral & till geochemical analyses; and to interpret the glacial history at local & regional scales. After introductory sections on regional geology, previous research, and sampling & survey methods, the paper summarizes preliminary results from field observations regarding generalized ice movements & glacial landforms.

Ice movement indicators have been carefully documented in the Arrowsmith River area of central mainland Nunavut, and this paper presents preliminary results of this research. It begins with background on the regional geological setting and on the field sampling methods used. Ice movement indicators & associated glacial landforms are then described, including striae, eskers, meltwater channels, moraine systems, and raised shorelines.

Observations & interpretations during mapping of the Walker Lake area, central Nunavut, allowed for the identification of three landforms requiring further investigation: eskers, transverse ridges, and irregular mounds. This paper describes & interprets each of these features, then develops a hypothesis that links their origin with the area's glacial history.

After an overview of the regional geological setting, this paper describes the geology of the three contrasting domains of the Committee Bay belt in central Nunavut. The first & largest section covers the central domain, which comprises four narrow supracrustal belts intruded by lenticular plutonic bodies. The remaining sections describe the northern crustal domain, dominated by metasedimentary rocks & granitoid plutons, and the south-east domain, dominated by granodiorite to granite batholiths that intrude rocks of the central domain.
