Sediments in the study area were deposited in a ramp setting where deltas prograde to the shelf edge. Sedimentation in this type of setting is not controlled by one large incised valley or canyon, but by multiple shallow gullies, channels and slope troughs. Channel complexes are shown in yellow, smaller channels are shown in white. Within the study area sandstone deposits were concentrated along two topographic ridges named Spine 1 and Spine 2 with only small pods of sandstone found in the drainage valley between the two ridges. These Spines represent the channel complexes formed by major fingers of the delta prograding to the shelf edge and beyond.
