geomembrane and the GCL was observed
at the cell during exhumation. Thin
stripes of relatively dry bentonite were
observed on the upper surface of the GCL
throughout the length of the slopes at the
site, likely corresponding to bentonite
deposited from rivulets of water flowing downslope. In addition, significant
accumulation of bentonite was present
along the toe of the east slope, forming a
wedge shape. The wedge feature consisted
of accumulation of bentonite between
the geomembrane and the GCL along
the slope length, with minimal bentonite
mass along the upper regions of the slope
and maximum depth of bentonite at the
toe of the slope (Figure 5). The wedge
feature extended approximately 295 feet
