23° on Nov. 13, 2019, the coldest reading for this week of the year since 1948. Next is 25° in 1963.
Bogue Chitto’s center stands about 420 ft above sea level. Within three miles the land runs from 370 ft to 500 ft, a difference of 130 ft: gently rolling country.
The section below crosses 2 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, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 21 mi of the line.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 3 mi of the line.

A raindrop that lands in Bogue Chitto reaches Lake Pontchartrain and the Gulf of America by way of the Bogue Chitto and the West Pearl: about 160 river miles.
130 miles of the trip are on the Bogue Chitto.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bogue Chitto; river miles along the main stem, rounded.
Bogue Chitto has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 38° in January. About 61 inches of rain fall in a normal year.
