Lookeba’s center stands about 1,350 ft above sea level. Within three miles the land runs from 1,310 ft to 1,570 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Dead Woman Mound, about 1,720 ft, 11 miles northwest.
Under the town center the state geologic map shows Marlow Formation (sandstone, siltstone), 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 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 9 mi of the line.
Sandstone. Age: Permian, 252 to 299 million years old. About 8 mi of the line.
Sandstone, siltstone. Age: Permian, 252 to 299 million years old. About 7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Lookeba reaches the Gulf of America by way of Sugar Creek, the Washita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 1,110 river miles.
680 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lookeba; river miles along the main stem, rounded.
