The Sunray 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.
Sunray’s center stands about 1,070 ft above sea level. Within three miles the land runs from 990 ft to 1,140 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Petticoat Hill, about 1,260 ft, 8 miles northeast.
Under the town center the state geologic map shows Garber Sandstone (sandstone, conglomerate), from the Permian, 252 to 299 million years old.
The section below crosses 9 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.
Sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 6 mi of the line.
Shale, sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 5 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Sandstone. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Permian, 252 to 299 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. 3 smaller units along the line are not listed.

A raindrop that lands in Sunray reaches the Gulf of America by way of Cow Creek, Beaver Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,030 river miles.
840 miles of the trip are on the Red River.
