Ellington’s center stands about 790 ft above sea level. Within three miles the land runs from 640 ft to 1,030 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Thorny Mountain, about 1,370 ft, 15 miles southwest.
Under the town center the state geologic map shows Eminence Dolomite, Potosi Dolomite (dolostone), from the Cambrian, 487 to 497 million years old.

Dolostone. Age: Cambrian, 487 to 497 million years old. About 16 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 8 mi of the line.

A raindrop that lands in Ellington reaches the Gulf of America by way of Logan Creek, the Black River, the White River and the Mississippi: about 1,140 river miles.
620 miles of the trip are on the Mississippi.
