The Ebro 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.
Ebro’s center stands about 80 ft above sea level. Within three miles the land runs from 10 ft to 110 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Laurel Hill, about 240 ft, 10 miles north-northwest.
Under the town center the state geologic map shows Citronelle Formation (sand), from the Late Pliocene, 2.6 to 3.6 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.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 10 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 9 mi of the line.
Clay, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sand, clay. Age: Middle Miocene to Early Pliocene, 3.6 to 16 million years old. About 2 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 Ebro reaches Choctawhatchee Bay and the Gulf of America by way of Pine Log Creek, the Sister and the Choctawhatchee: about 20 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ebro; river miles along the main stem, rounded.
