Tylertown’s center stands about 320 ft above sea level. Within three miles the land runs from 250 ft to 400 ft, a difference of 150 ft: gently rolling country.
The section below crosses 4 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.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 14 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 6 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 0.8 mi of the line.

A raindrop that lands in Tylertown reaches Lake Pontchartrain and the Gulf of America by way of Dry Creek, Magees Creek, the Bogue Chitto and the West Pearl: about 120 river miles.
80 miles of the trip are on the Bogue Chitto.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tylertown; river miles along the main stem, rounded.
