Last weekend I was at the Society for Pennsylvania Archaeology meetings,
and there was a paper in which they mentioned the effect of seasonal
draw-downs (in which a lake level is lowered in anticipation of flood
season). Sites would normally have been found in the old plow zone, but
the draw-down effect was describved as being like pulling the plug in a
bath tub. The topsoil had been drained away from the shallower areas of
the lake, leaving only subsoil, and had accumulated in the lower part of
the lake, leaving thicker sediments overlying the original surface
there. Interesting.
