Fort Covington’s center stands about 180 ft above sea level. Within three miles the land runs from 150 ft to 230 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is The Pinnacle, about 990 ft, 15 miles southeast.
Under the town center the state geologic map shows Beekmantown Group (in part) (dolostone, limestone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Early Ordovician, 471 to 487 million years old. About 6 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 3 mi of the line.
Dolostone. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 3 mi of the line.
Amphibolite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.2 mi of the line.
