Science Hill’s center stands about 1,090 ft above sea level. Within three miles the land runs from 870 ft to 1,230 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Green River Knob, about 1,780 ft, 12 miles west.
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 33×. 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 13 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 1 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Science Hill reaches the Gulf of America by way of Holtzclaw Branch, Pitman Creek, the Cumberland, the Ohio and the Mississippi: about 1,560 river miles.
Lakes on the way: Bards Lake, Lake Cumberland and Cordell Hull Reservoir.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Science Hill; river miles along the main stem, rounded.
