Mooringsport’s center stands about 220 ft above sea level. Within three miles the land runs from 160 ft to 340 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Pine Hills, about 410 ft, 9 miles southeast.
Under the town center the state geologic map shows Wilcox Group (undifferentiated) (sand, clay, lignite), from the Paleocene, 56 to 66 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay, lignite. Age: Paleocene, 56 to 66 million years old. About 9 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Black-shale. Age: Paleocene, 56 to 66 million years old. About 3 mi of the line.
Clay. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Mooringsport reaches the Gulf of America by way of Walnut Bayou, Twelvemile Bayou, Cross Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 430 river miles.
Lake on the way: Clear Lake.
260 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mooringsport; river miles along the main stem, rounded.
