Celina’s center stands about 560 ft above sea level. Within three miles the land runs from 510 ft to 970 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Miller Mountain, about 1,670 ft, 13 miles southeast.
Under the town center the state geologic map shows Alluvial deposits (fine-detrital, coarse-detrital), from the Quaternary, less than 2.6 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Chert. Age: Carboniferous, 324 to 359 million years old. About 5 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 6 smaller units along the line are not listed.
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 Celina reaches the Gulf of America by way of the Cumberland, the Ohio and the Mississippi: about 1,410 river miles.
Lakes on the way: Bards Lake 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 Celina; river miles along the main stem, rounded.
