The Clio 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.
21° on Nov. 15, 1969, the coldest reading for this week of the year since 1928. Next is 23° in 2019.
Clio’s center stands about 540 ft above sea level. Within three miles the land runs from 370 ft to 550 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Wilcox Group; Tuscahoma Sand (silt, clay), from the Paleocene, 56 to 66 million years old.
The section below crosses 7 rock units mapped at the surface.
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.
Silt, clay. Age: Paleocene, 56 to 66 million years old. About 7 mi of the line.
Limestone. Age: Paleocene, 56 to 66 million years old. About 5 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Clay, sand. Age: Paleocene, 56 to 66 million years old. About 5 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.
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 Clio reaches Choctawhatchee Bay and the Gulf of America by way of Foulk Creek, Big Creek, the Pea and the Choctawhatchee: about 200 river miles.
110 miles of the trip are on the Pea.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clio; river miles along the main stem, rounded.
Clio has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 37° in January. About 56 inches of rain fall in a normal year.
On November 14 Clio normally reaches 69° and falls to 45°. The record high is 85°, in 1959; the record low 26°, in 2019. The most rain on this date, 2.00 in, fell in 1930.
Normals 1991–2020 and records since 1928 at Clayton, 15 miles northeast. NOAA, through RCC-ACIS.
