The North Carrollton plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
16° on Nov. 13, 2019, the coldest reading for this week of the year since 1948. Next is 20° in 1997.
North Carrollton’s center stands about 230 ft above sea level. Within three miles the land runs from 220 ft to 420 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Millers Hill, about 400 ft, 12 miles southwest.
Under the town center the state geologic map shows Kosciusko formation (sand, clay), from the Eocene, 34 to 56 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. 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, clay. Age: Eocene, 34 to 56 million years old. About 13 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 9 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

A raindrop that lands in North Carrollton reaches the Gulf of America by way of Beasley Creek, Big Sand Creek, Pelucia Bayou, the Yalobusha, the Yazoo and the Mississippi: about 640 river miles.
450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Carrollton; river miles along the main stem, rounded.
North Carrollton has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 35° in January. About 52 inches of rain fall in a normal year.
On November 14 North Carrollton normally reaches 66° and falls to 42°. The record high is 86°, in 1955; the record low 21°, in 2014. The most rain on this date, 2.67 in, fell in 1998.
