Fort Green Springs’s center stands about 120 ft above sea level. Within three miles the land runs from 100 ft to 150 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Hawthorn Group, Peace River Formation, Bone Valley Member (sand, clay, phosphorite), from the Middle Miocene to Pliocene, 2.6 to 16 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 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, phosphorite. Age: Middle Miocene to Pliocene, 2.6 to 16 million years old. About 20 mi of the line.
Sand, clay, dolostone. Age: Middle Miocene to Pliocene, 2.6 to 16 million years old. About 3 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Fort Green Springs reaches the Gulf of America by way of Payne Creek and the Peace: about 90 river miles.
