85° on Nov. 11, 2002, the hottest reading for this week of the year since 1883. Next is 84° in 1931.
Michie’s center stands about 620 ft above sea level. Within three miles the land runs from 420 ft to 630 ft, a difference of 210 ft: rolling country.
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 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.
Fine-detrital, coarse-detrital. Age: Tertiary to Quaternary, less than 66 million years old. About 7 mi of the line.
Marl. Age: Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Chalk. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Sand, clay. Age: Late Cretaceous, 66 to 100 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Michie reaches the Gulf of America by way of Lick Creek, the Tennessee, the Ohio and the Mississippi: about 1,230 river miles.
Lake on the way: Pickwick Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Michie; river miles along the main stem, rounded.
Michie has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 30° in January. About 59 inches of rain fall in a normal year.
On November 14 Michie normally reaches 64° and falls to 40°. The record high is 82°, in 1931; the record low 15°, in 2019. The most rain on this date, 2.80 in, fell in 1989.
Normals 1991–2020 and records since 1883 at Savannah 6 SW, 9 miles northeast, 170 ft lower. NOAA, through RCC-ACIS.
