till-floored lake plain

till-floored lake plain
   [ soil survey ]
   A glaciated land area that has 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, and has thin (e.g. H 1-3 m), continuous or discontinuous lacustrine sediment atop the till. Topography that once existed as islands may exhibit shore features (e.g., wave-cut scarps, strandlines, beach deposits).
