The Prentiss 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.
Prentiss’s center stands about 400 ft above sea level. Within three miles the land runs from 300 ft to 520 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Pascagoula and Hattiesburg formation (clay, sand), from the Miocene, 5.3 to 23 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. 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 10 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 Prentiss reaches the Gulf of America by way of White Sand Creek and the Pearl: about 200 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Prentiss; river miles along the main stem, rounded.
