Nocona Hills’s center stands about 900 ft above sea level. Within three miles the land runs from 800 ft to 990 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Mount View, about 1,300 ft, 9 miles southeast.
Under the town center the state geologic map shows Nocona Formation (claystone), from the Permian, 252 to 299 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone. Age: Permian, 252 to 299 million years old. About 10 mi of the line.
Sandstone, claystone. Age: Early Cretaceous, 100 to 145 million years old. About 8 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Limestone. Age: Early Cretaceous, 100 to 113 million years old. About 0.7 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 0.6 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 Nocona Hills reaches the Gulf of America by way of Farmers Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 940 river miles.
800 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Nocona Hills; river miles along the main stem, rounded.
