Also known as Maine Loc. 2
Where: Portland County, Maine (43.6° N, 70.3° W: paleocoordinates 43.6° N, 70.3° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Presumpscot Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)
• LITHOSTRATIGRAPHY: No lithostratigraphic unit reported in text. Bloom (1960) assigned the name "Presumpscot Fm" to the sheet of emerged marine sediments that blankets the coastal region of southwestern Maine.
