Dighton’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 190 ft, a difference of 190 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Copicut Hill, about 360 ft, 7 miles south-southeast.
Under the town center the state geologic map shows Dighton Conglomerate, from the Carboniferous, 299 to 324 million years old.
The section below crosses 2 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.
Sandstone, graywacke. Age: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Conglomerate. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Dighton reaches Narragansett Bay and the Atlantic Ocean by way of Muddy Cove Brook and the Taunton: about 12 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dighton; river miles along the main stem, rounded.
