Lamont’s center stands about 90 ft above sea level. Within three miles the land runs from 60 ft to 160 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Texas Hill, about 280 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Hawthorn Group, Torreya Formation (sandstone, limestone), from the Middle Miocene, 12 to 16 million years old.
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.
Sandstone, limestone. Age: Middle Miocene, 12 to 16 million years old. About 11 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 8 mi of the line.
Sand, clay, gravel. Age: Late Pliocene, 2.6 to 3.6 million years old. About 4 mi of the line.
Limestone, dolostone. Age: Oligocene, 23 to 34 million years old. About 0.7 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 Lamont reaches the Gulf of America by way of the Aucilla: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lamont; river miles along the main stem, rounded.
