Westport’s center stands about 130 ft above sea level. Within three miles the land runs from 0 ft to 250 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Copicut Hill, about 360 ft, 10 miles north.
Under the town center the state geologic map shows Alaskite (alkali-granite), from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Westport reaches the Atlantic Ocean by way of Snell Creek and the East Branch Westport: about 7 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Westport; river miles along the main stem, rounded.
