Abstract
To the author's knowledge, relict iceberg furrows on the floor of former glacial lakes in Canada have not yet been reported. Many examples of recent and relict iceberg features on sea floors are known in the Arctic Ocean ... and in the North Atlantic Ocean .... In addition Berkson and Clay (1973) have reported iceberg furrows on the floor of Lake Superior, and Clayton et al (1965) have interpreted the intersecting minor lineations on Lake Agassiz plain as grooves made by drifting ice floes. Examples of modern grooving by drift-ice in lake bottom sediments are given by Koshechkin (1958) for the north Caspian Sea, by Weber (1958) for the Great Slave Lake, and by Mollard (1973) for the Great Slave Lake, and lakes Manitoba and Montreal (Saskatchewan). Ice-made grooves in the tidal flats of the Lower St. Lawrence Estuary have been fully described by Dionne (1968, 1969, 1971). This paper reports furrows observed on air photos and in the field of a clay plain in northwestern Quebec and adjacent Ontario.
