Naples’s center stands about 310 ft above sea level. Within three miles the land runs from 260 ft to 670 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Pleasant Mountain, about 1,990 ft, 11 miles west-northwest.
Under the town center the state geologic map shows Carboniferous alkali feldspar granite (muscovite accessory mineral), from the Carboniferous, 299 to 359 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 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Carboniferous, 299 to 359 million years old. About 22 mi of the line.
Foid-syenite. Age: Mesozoic, 66 to 252 million years old. About 2 mi of the line.

A raindrop that lands in Naples reaches the Atlantic Ocean by way of Whitney Brook and the Presumpscot: about 45 river miles.
Lake on the way: Sebago Lake Basin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Naples; river miles along the main stem, rounded.
