10° on Nov. 12, 2019, the coldest reading for this week of the year since 1987. Next is 13° in 2018.
LaBarque Creek’s center stands about 590 ft above sea level. Within three miles the land runs from 440 ft to 850 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Tavern Rock, about 880 ft, 14 miles north-northwest.
Under the town center the state geologic map shows St. Peter Sandstone, Everton Formation (dolostone, sandstone, limestone), from the Early Ordovician to Middle Ordovician, 459 to 487 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 7 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 6 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 4 mi of the line.
Dolostone, limestone, shale. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Dolostone, sandstone, limestone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 2 mi of the line.
Sandstone, chert. Age: Early Ordovician, 471 to 487 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 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 LaBarque Creek reaches the Gulf of America by way of La Barque Creek, the Meramec and the Mississippi: about 1,180 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of LaBarque Creek; river miles along the main stem, rounded.
LaBarque Creek has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 22° in January. About 40 inches of rain fall in a normal year.
On November 14 LaBarque Creek normally reaches 57° and falls to 35°. The record high is 80°, in 2025; the record low 13°, in 2018. The most rain on this date, 2.08 in, fell in 1993.
Normals 1991–2020 and records since 1987 at St Louis Spirit Of St Louis Airport, 17 miles north, 130 ft lower. NOAA, through RCC-ACIS.
