The oblique aerial photograph in [[:file:exploring-for-structural-traps_fig20-12.png|Figure 9]] shows structures in the upper plate of the Absaroka thrust in the central Wyoming thrust belt, updip and along strike of the producing structures in the same thrust sheet to the south. (See [[:file:exploring-for-structural-traps_fig20-6.jpg|Figure 3]] for the location.)

The tectonic setting and stratigraphic section are similar to the producing trend; therefore, the deformation features of the exposed structures can be used as analogs for producing structures to the south. The numbered ridge lines in the photo provide a set of natural serial cross sections through the structures ([[:file:exploring-for-structural-traps_fig20-13.png|Figure 10]]).

[[:file:exploring-for-structural-traps_fig20-14.png|Figure 10]] shows structures in the upper plate of the Absaroka thrust fault on the south side of ridge line 4 in [[:file:exploring-for-structural-traps_fig20-12.png|Figure 9]]. The white outcrops in the valley in the left foreground are tightly folded Ordovician Bighorn dolomite.
