77° on Nov. 14, 1999, the hottest reading for this week of the year since 1895. Next is 76° in 1911.
Lowpoint’s center stands about 720 ft above sea level. Within three miles the land runs from 660 ft to 800 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Bond Formation (shale, sandstone, limestone), from the Late Pennsylvanian, 304 to 307 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 12 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 6 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 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 Lowpoint reaches the Gulf of America by way of Richland Creek, the Illinois and the Mississippi: about 1,380 river miles.
Lake on the way: Peoria Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lowpoint; river miles along the main stem, rounded.
Lowpoint has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 15° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Lowpoint normally reaches 51° and falls to 32°. The record high is 77°, in 1999; the record low 6°, in 1986. The most rain on this date, 1.17 in, fell in 1926.
Normals 1991–2020 and records since 1895 at Minonk, 15 miles east. NOAA, through RCC-ACIS.
