wave-worked till plain

wave-worked till plain
   A glaciated land area that has the characteristics of a till plain, but that was also inundated by a glacial lake. The area possesses a gently undulating till-topography rather than a distinctive, low-relief lake plain surface. Lacustrine sediments, however, are absent or occur only sparsely, but a wave/current-modified, surficial mantle may commonly exist atop the till. Topographic highs, which were once islands, may possess shore features (e.g., wave-cut scarps, strandlines, beach deposits).
   Compare: till-floored lake plain.
