Two Rivers’s center stands about 590 ft above sea level. Within three miles the land runs from 570 ft to 660 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Silurian, undivided (dolostone), from the Silurian, 422 to 445 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 51×. 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 Two Rivers reaches Lake Michigan by way of the West Twin: about 2 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
