Suttons Bay’s center stands about 650 ft above sea level. Within three miles the land runs from 570 ft to 990 ft, a difference of 420 ft: hilly country. The highest named summit within 15 miles is Fouch Hill, about 1,070 ft, 11 miles south-southwest.
Under the town center the state geologic map shows Antrim Shale (black-shale), from the Late Devonian, 359 to 384 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 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 8 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.

Rain that falls on Suttons Bay runs straight into Lake Michigan. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
