The Hodgenville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Hodgenville’s center stands about 730 ft above sea level. Within three miles the land runs from 690 ft to 860 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Akin Knob, about 1,010 ft, 15 miles south-southeast.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 19 mi of the line.
Shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 2 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.9 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.6 mi of the line.

A raindrop that lands in Hodgenville reaches the Gulf of America by way of the North Fork Nolin, the Nolin, the Green River, the Ohio and the Mississippi: about 1,460 river miles.
970 miles of the trip are on the Mississippi.
