Bellevue’s center stands about 1,030 ft above sea level. Within three miles the land runs from 910 ft to 1,060 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Galliher Mountain, about 1,230 ft, 14 miles south.
Under the town center the state geologic map shows Archer City Formation (black-shale), from the Permian, 252 to 299 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. 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: Permian, 252 to 299 million years old. About 11 mi of the line.
Sandstone. Age: Carboniferous to Permian, 252 to 324 million years old. About 9 mi of the line.
Claystone. Age: Permian, 252 to 299 million years old. About 4 mi of the line.

A raindrop that lands in Bellevue reaches the Gulf of America by way of West Belknap Creek, Belknap Creek, the Red River, the Atchafalaya and the Lower Atchafalaya: about 990 river miles.
820 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bellevue; river miles along the main stem, rounded.
