Figure 8. Shaded relief map of surficial geology of the offshore from Casco Bay (left) to Southport Island (right). The Kennebec River is in the top center of the map and the Sheepscot River is in the top right. Green colors represent sand (olive green) and fine gravel (dark green) of the Kennebec paleodelta. Pink colors are muddy sediment and the orange color is bedrock. Contours are in meters. Map created by W. A. Barnhardt and based on a portion of Open-File Map 96-9 of the Maine Geological Survey (Barnhardt and others, 1996).
