Robbinston’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 440 ft, a difference of 440 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Carlisle Mountain, about 570 ft, 6 miles southwest.
Under the town center the state geologic map shows Devonian granite (hornblende accessory mineral), from the Devonian, 359 to 422 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Devonian, 359 to 422 million years old. About 5 mi of the line.

A raindrop that lands in Robbinston reaches the Atlantic Ocean by way of the Eastern Stream, the Western Stream and the Saint Croix: about 7 river miles.
