20° on Nov. 16, 2019, the coldest reading for this week of the year since 1961. Next is 25° in 1997.
Grove Hill’s center stands about 510 ft above sea level. Within three miles the land runs from 270 ft to 510 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Miocene Series undifferentiated (sand, clay), from the Miocene to Pliocene, 2.6 to 23 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 46×. 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: Miocene to Pliocene, 2.6 to 23 million years old. About 11 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 6 mi of the line.
Clay, limestone. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Limestone. Age: Oligocene, 23 to 34 million years old. About 1 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1.0 mi of the line.
Claystone. Age: Eocene, 34 to 56 million years old. About 0.6 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 Grove Hill reaches Mobile Bay and the Gulf of America by way of James Creek, Bassett Creek, the Tombigbee and the Mobile: about 130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grove Hill; river miles along the main stem, rounded.
Grove Hill has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 36° in January. About 60 inches of rain fall in a normal year.
On November 14 Grove Hill normally reaches 69° and falls to 43°. The record high is 84°, in 1993; the record low 26°, in 2013. The most rain on this date, 2.00 in, fell in 1961.
Normals 1991–2020 and records since 1961 at Jackson, 15 miles southwest, 290 ft lower. NOAA, through RCC-ACIS.
