AbstractStudy of ice-movement indicators in the Darby Lake (NTS 56 N) and Arrowsmith River (NTS 56-O/9-16) map areas revealed a complex ice-flow history involving four phases. The oldest phase was north-northeastward to northeastward, and likely reflects ice flow during the last glacial maximum. This was followed by divergent flow, where ice in the western 56 N map area flowed north-northwest, and ice in
the central to eastern 56 N, and in 56-O (north) map areas, flowed north-northeast. The third phase involved a shift of Darby Lake and western Arrowsmith River ice-flow directions to north-northeast and to the northeast in eastern 56-O (north). The final phase was a late-stage advance into 56 N /1 and 2.
As part of a reconnaissance-scale drift-prospecting program, 92 till samples were collected and analyzed for heavy-mineral content, texture, carbonate content, pebble lithology, and trace/major elements. The study area was subjected to significant marine incursion, particularly in the major river valleys where marine sediments were found at elevations ranging between 92 m to 223 m a.s.l.
