5.01 inches of rain fell in two days, the most for this week of the year since records began in 1959. The next wettest, 3.24 inches, fell in 1993.
Lamb’s center stands about 480 ft above sea level. Within three miles the land runs from 420 ft to 890 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Mount Byrd, about 920 ft, 11 miles west.
Under the town center the state geologic map shows Kope Formation (shale), from the Ordovician, 445 to 487 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Lamb reaches the Gulf of America by way of Green Valley Creek, the Ohio and the Mississippi: about 1,400 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lamb; river miles along the main stem, rounded.
Lamb has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 23° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Lamb normally reaches 57° and falls to 34°. The record high is 74°, in 2011; the record low 12°, in 1986. The most rain on this date, 1.73 in, fell in 1972.
Normals 1991–2020 and records since 1959 at Warsaw Markland Dam, 13 miles east-northeast. NOAA, through RCC-ACIS.
