AbstractIn the summer of 2018, fieldwork was conducted on the north coast of Fury and Hecla Strait on northwestern Baffin Island, Nunavut, to document glacial dynamics at a regional scale. Glacial geomorphology has been interpreted and generalized from field observations and integrated with elements from previous surficial geology maps and field observations, and the analysis of pebble lithology in till. The combined use of satellite imagery (SPOT 6) and high-resolution digital elevation and bathymetric models has increased the level of mapping detail. Glaciodynamic mapping shows important contrasts in glacial erosion and transport in the study area. A synthesis of new and published datasets of clast-lithology counts indicates the importance of the main ice-flow phase in the region, and highlights the presence of an ice divide over the Saputing Lake-Gifford River area and of ice streams in the Bernier Bay, Fury and Hecla Strait and Whyte Inlet areas.
Summary(Plain Language Summary, not published)
New glacial geology fieldwork in the area north of the Fury and Hecla Strait are described in this report. It also provides a synthesis of pre-existing works in the region. Till samples were collected, and new glacial striations and features are mapped. The glacial erosion and glacial transport are important factors in the geomorphology of the areas. Carbonate rocks and sandstones were transported over great distances. One hematitic iron stone glacial erratic was found.
