4.05 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 3.87 inches, fell in 1993.
Raymond’s center stands about 320 ft above sea level. Within three miles the land runs from 220 ft to 410 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Catahoula formation (sand), from the Miocene, 5.3 to 23 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 60×. 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. Age: Miocene, 5.3 to 23 million years old. About 15 mi of the line.
Limestone. Age: Oligocene, 23 to 34 million years old. About 4 mi of the line.
Clay. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Sand, clay. Age: Oligocene, 23 to 34 million years old. About 1 mi of the line.

A raindrop that lands in Raymond reaches the Gulf of America by way of Snake Creek, Bakers Creek, Fourteenmile Creek, the Big Black and the Mississippi: about 510 river miles.
420 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Raymond; river miles along the main stem, rounded.
Raymond has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 36° in January. About 57 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Raymond normally reaches 68° and falls to 44°. The record high is 88°, in 1921; the record low 21°, in 1907. The most rain on this date, 2.27 in, fell in 1993.
