(C) High-aspect-ratio, sandstone-dominated channel-system deposits (CSC3), DeCourcy Formation, south coast of Saturna Island (48.7728°N, 123.1903°W). White lines demarcate bounding surfaces of channel-form bodies. (D) Sandstone-dominated tabular components (TSC1), southwest sea cliffs of Valdes Island (49.0905°N, 123.6865°W). (E) Heterolithic (TSC2) and overlying siltstone-dominated tabular components (TSC3), Northumberland Formation, Gabriola Island (49.1296°N, 123.7591°W).

(B) Simplified interpretation of the same projected data that show the distribution of stratigraphic components and outline the limits of channel-system deposits identified by stratigraphic and age relationships. Note that small, local structural deformations/variations were not removed in detailed projections (e.g., Valdes Island and northern Galiano Island) and that there is a horizontal scale break between Hornby Island and Gabriola Island where a large area without outcrop is removed from the cross section.
