Figure 25.  Seismic expression of Beaufortian clinoform lowstand wedge (highlighted in blue), which pinches out via updip onlap to north and thins gradually downdip to south.  Note internal reflection that appears to onlap basal sequence boundary at mile 87 and that pinches out at mile 83.  Beaufortian clinoform play interval is indicated by red dashed lines and arrows.  This seismic line segment also has a feature (highlighted in yellow) near the top of sequence set K2 that is interpreted as an incision similar to that shown in Fig. 16C.  Labeled stratigraphic horizons:  SF = top Shublik Formation; K1 = top Kingak K1 sequence set; K2 = top Kingak K2 sequence set; LCU = Lower Cretaceous unconformity.
