Figure 21. Upright folds in the Bucksport Formation at Pemaquid Point Lighthouse. This photograph looks directly along the crest of an F2 antiform. In the middle distance the form of the fold is clearly visible. Thin pegmatite sills are common along bedding contacts. On the skyline to the right is a large ridge underlain by a pegmatite dike.
