Newport’s center stands about 1,060 ft above sea level. Within three miles the land runs from 1,010 ft to 1,530 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Mount Cammerer, about 4,900 ft, 14 miles south.
Under the town center the state geologic map shows Knox Group, including Jonesboro Limestone, Newala Formation, Mascot Dolomite, Kingsport Formation, Longview Dolomite, Chepultepec Dolomite, Copper Ridge Dolomite, Conococheague Limestone (limestone, dolostone), from the Cambrian to Ordovician, 445 to 542 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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. Age: Ordovician, 445 to 487 million years old. About 11 mi of the line.
Limestone, dolostone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 6 mi of the line.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Shale. Age: Precambrian. About 2 mi of the line.
Age: Precambrian. About 2 mi of the line.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 0.9 mi of the line.

A raindrop that lands in Newport reaches the Gulf of America by way of the Pigeon, the French Broad, the Tennessee, the Ohio and the Mississippi: about 1,740 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.
