22° on Nov. 15, 1940, the coldest reading for this week of the year since 1892. Next is 23° in 1916.
Jeanerette’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 60 ft, a difference of 60 ft: nearly flat ground.
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 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.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Silt, clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Clay, silt. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
