5° on Nov. 12, 2019, the coldest reading for this week of the year since 1935. Next is 12° in 1996.
Metamora’s center stands about 820 ft above sea level. Within three miles the land runs from 690 ft to 830 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, 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 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.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 10 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 9 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 5 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 Metamora reaches the Gulf of America by way of Partridge 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 Metamora; river miles along the main stem, rounded.
Metamora has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 17° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 38 inches of water.
Normals 1991–2020 and records since 1935 at Congerville 2 NW, 13 miles south-southeast, 180 ft lower. NOAA, through RCC-ACIS.
