18° on Nov. 15, 1969, the coldest reading for this week of the year since 1899. Next is 20° in 1933.
Lesslie’s center stands about 720 ft above sea level. Within three miles the land runs from 560 ft to 730 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Felsic metavolcanic rocks and felsic gneiss interpreted to the metavolcanics (metavolcanic, gneiss), from the Neoproterozoic to Ordovician, 445 to 1,000 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagranite, metadiorite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metavolcanic, gneiss. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 4 mi of the line.
Gabbro. Age: Silurian to Devonian, 359 to 445 million years old. About 4 mi of the line.
Gabbro. Age: Silurian to Devonian, 359 to 445 million years old. About 4 mi of the line.
Phyllonite, schist. Age: Paleozoic, 252 to 542 million years old. About 3 mi of the line.
Metagranite. Age: Cambrian to Ordovician, 445 to 542 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. 3 smaller units 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 Lesslie reaches the Atlantic Ocean by way of Sixmile Creek, the Catawba, the Wateree, the Congaree, the Santee and the South Santee: about 260 river miles.
Lake on the way: Lib Pines Lake.
90 miles of the trip are on the Wateree.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lesslie; river miles along the main stem, rounded.
Lesslie has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 32° in January. About 43 inches of rain fall in a normal year.
On November 14 Lesslie normally reaches 64° and falls to 41°. The record high is 81°, in 1931; the record low 21°, in 2013. The most rain on this date, 1.33 in, fell in 1940.
