| 520 | 3 |a"The Pine Point region is of very low relief and characterized by black spruce bogs with local relief not exceeding 20 m. During Wisconsin time, the Breynat Point map sheet was actively and continuously glaciated by the Laurentide Ice Sheet which was generally flowing to the west. Multiple till units were observed in the open pits, however only the uppermost unit was mapped at surface. The map area was completely inundated by proglacial Lake McConnell which formed during deglaciation, glaciolacustrine sediments are the dominant materials that occur as beach ridges and littoral sediments. Reworked beach ridges form eolian dunes up to 15 m high. Raised strandlines formed by earlier phases of Great Slave Lake mark the former isostatic rebound of the land surface. Organic deposits are extensive with mature peatlands and fens, which are underlain by discontinuous permafrost with active thermokarst. Abandoned open pits and waste piles pockmark the former Pine Point mining district"--Abstract. |
