Chillicothe’s center stands about 1,400 ft above sea level. Within three miles the land runs from 1,360 ft to 1,480 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Big Mound, about 1,710 ft, 8 miles west-southwest.
Under the town center the state geologic map shows Sand sheet deposits, from the Holocene, less than 12,000 years old.
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 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.
Sand. Age: Holocene, less than 12,000 years old. About 13 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 7 mi of the line.
Claystone. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.5 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 Chillicothe reaches the Gulf of America by way of Wanderers Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chillicothe; river miles along the main stem, rounded.
