Lockport Heights’s center stands about 6 ft above sea level. Within three miles the land runs from 0 ft to 20 ft, a difference of 20 ft: nearly flat ground. Open water lies within three miles.
Under the town center the state geologic map shows Natural Levees (silt, clay), from the Holocene, less than 12,000 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.
Silt, clay. Age: Holocene, less than 12,000 years old. About 9 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 8 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 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.

A raindrop that lands in Lockport Heights reaches the Gulf of America by way of the Bayou Lafourche: about 50 river miles.
