The Gene Autry 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.
Gene Autry’s center stands about 810 ft above sea level. Within three miles the land runs from 690 ft to 1,060 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Robbers Roost, about 1,070 ft, 13 miles north-northeast.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 12 mi of the line.
Limestone, dolostone. Age: Cambrian, 487 to 497 million years old. About 8 mi of the line.
Sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 0.9 mi of the line.
Limestone, dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 0.9 mi of the line.
Limestone, conglomerate, dolostone. Age: Early Ordovician, 471 to 487 million years old. About 0.8 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million 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. 2 smaller units along the line are not listed.

A raindrop that lands in Gene Autry reaches the Gulf of America by way of Big Branch, the Washita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 890 river miles.
680 miles of the trip are on the Red River.
