context_page_description: Lake Nipisso is a 40 square kilometres lake in a remote part of the Côte-Nord region of Quebec, Canada.
context_section_description: The region is near the southern border of the Canadian Shield, and is a rolling to rugged upland, with mountains reaching 2,100 feet (640 m).
  The Nipissis and Nipisso run through deep valleys in this upland.
  Lake Nipisso is in what was once a deeper valley parallel to the Nipissis-Wacouno valley.
  The valley was filled by glaciers with boulders and pebbles in a matrix of silt and sand.
  Subsequently these deposits were reworked by the present river.
  In the south of the Nipisso Lake area there are signs of intense glacial erosion, but there are few glacial deposits.
  North of 50°50' there are greater quantities of glacial debris, with large amounts of sand and gravel in the valleys, and many sand plains.
  Just east of the north end of Lake Nipisso there are three crescent-shaped ridges of sand and gravel about 1,000 feet (300 m) long, 40 feet (12 m) wide and 20 feet (6.1 m) high. These are at right angles to the direction of the Laurentide Ice Sheet movement, and may be recessional moraines.
