Eminence’s center stands about 920 ft above sea level. Within three miles the land runs from 790 ft to 940 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Jeptha Knob, about 1,200 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Bull Fork Formation (limestone), from the Ordovician, 445 to 487 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. 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: Ordovician, 445 to 487 million years old. About 7 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 0.7 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 Eminence reaches the Gulf of America by way of Fox Run, Bullskin Creek, Brashears Creek, the Salt River, the Ohio and the Mississippi: about 1,420 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 Eminence; river miles along the main stem, rounded.
