 Glaciolacustrine plain formations can be found in a variety of places.For instance, Lake Agassiz-Ojibway Basin in northwestern Quebec is a good example of lacustrine plain formation caused by the ice readvance and drainage of Lake Ojibway.By analyzing the varve sequences and dividing them into the Matagami section and La Reine section, researchers were able to determine the time of occurrence for a major ice readvance event in the area and two drainage events in the lake.
