18° on Nov. 13, 2019, the coldest reading for this week of the year since 1930. Next is 19° in 1940.
Louise’s center stands about 110 ft above sea level. Within three miles the land runs from 90 ft to 140 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Alluvium (fine-detrital, coarse-detrital), from the Holocene, less than 12,000 years old.
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.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 24 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 Louise reaches the Gulf of America by way of Silver Creek, the Big Sunflower, the Yazoo and the Mississippi: about 530 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Louise; river miles along the main stem, rounded.
Louise has a humid subtropical climate. Summer afternoons average 91° in August; winter nights fall to about 36° in January. About 57 inches of rain fall in a normal year.
