Canal Lewisville’s center stands about 770 ft above sea level. Within three miles the land runs from 740 ft to 1,070 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Hardscrabble Hill, about 1,110 ft, 2 miles south-southeast.
Under the town center the state geologic map shows Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided (shale, siltstone, sandstone), from the Devonian to Carboniferous, 324 to 422 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 34×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 17 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 7 mi of the line.

A raindrop that lands in Canal Lewisville reaches the Gulf of America by way of the Tuscarawas, the Muskingum, the Ohio and the Mississippi: about 1,890 river miles.
970 miles of the trip are on the Mississippi.
