The Vanceboro plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Vanceboro’s center stands about 410 ft above sea level. Within three miles the land runs from 370 ft to 760 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Greenland Mountain, about 1,200 ft, 15 miles west.
Under the town center the state geologic map shows Devonian - Ordovician Flume Ridge Formation (graywacke), from the Ordovician to Silurian, 422 to 487 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Graywacke. Age: Ordovician to Silurian, 422 to 487 million years old. About 12 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Vanceboro reaches the Atlantic Ocean by way of Salmon Brook and the Saint Croix: about 75 river miles.
