Figure 4A. Map of the NPRA showing generalized thickness
(in feet) of Beaufortian sequence set K1, public domain seismic grid used to
map sequence sets, well penetrations of K1, and wells with public domain cores
in K1. Arrows indicate dip directions
of K1 clinoforms, with base and tip of each arrow showing approximate updip
(proximal) and downdip (distal) extent of clinoforms.
