Figure 4. This brown-weathering dike intrudes across the bedding of the Kittery Formation. The dike is broken by a small fault, so that the dike in the foreground does not continue all the way to the vegetation, but is offset to the right. The fault creates an imperfection in the rock that is exploited by wave erosion to produce a small notch in the bedrock surface.
