4.20 inches of rain fell in two days, the most for this week of the year since records began in 1904. The next wettest, 4.03 inches, fell in 1958.
Mount Olive’s center stands about 410 ft above sea level. Within three miles the land runs from 300 ft to 1,040 ft, a difference of 740 ft: hilly country. The highest named summit within 15 miles is Irons Mountain, about 1,600 ft, 11 miles south-southeast.
Under the town center the state geologic map shows St. Peter Sanstone and Everton Formation (Middle Ordovician) (sandstone, dolostone), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, dolostone. Age: Middle Ordovician, 459 to 471 million years old. About 17 mi of the line.
Limestone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 3 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Sandstone, shale, limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 0.5 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.3 mi of the line.

A raindrop that lands in Mount Olive reaches the Gulf of America by way of the White River and the Mississippi: about 960 river miles.
620 miles of the trip are on the Mississippi.

Mount Olive has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 25° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Mount Olive normally reaches 59° and falls to 35°. The record high is 82°, in 2007; the record low 13°, in 2019. The most rain on this date, 1.13 in, fell in 1996.
Normals 1991–2020 and records since 1904 at Calico Rock 2 WSW, 8 miles north-northwest. NOAA, through RCC-ACIS.
