The Paris plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Paris’s center stands about 610 ft above sea level. Within three miles the land runs from 500 ft to 610 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Blossom Sand (sandstone), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Marlstone, claystone. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Claystone. Age: Late Cretaceous, 66 to 72 million years old. About 3 mi of the line.
Black-shale, siltstone. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit 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 Paris reaches the Gulf of America by way of Stillhouse Creek, Pine Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 730 river miles.
560 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Paris; river miles along the main stem, rounded.
