The Hardinsburg 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.
Hardinsburg’s center stands about 690 ft above sea level. Within three miles the land runs from 640 ft to 930 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Smith Hill, about 1,000 ft, 8 miles north-northeast.
Under the town center the state geologic map shows Blue River Group (limestone), from the Carboniferous, 324 to 359 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 52×. 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 15 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 6 mi of the line.
Sandstone, limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
