Olive Hill’s center stands about 760 ft above sea level. Within three miles the land runs from 770 ft to 1,100 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Locust Knob, about 1,300 ft, 14 miles southeast.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. 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: Devonian to Carboniferous, 324 to 422 million years old. About 12 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 5 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 Olive Hill reaches the Gulf of America by way of Mill Branch, Tygarts Creek, the Ohio and the Mississippi: about 1,670 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Olive Hill; river miles along the main stem, rounded.
