The La Rose plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
77° on Nov. 14, 1999, the hottest reading for this week of the year since 1895. Next is 76° in 1911.
La Rose’s center stands about 670 ft above sea level. Within three miles the land runs from 600 ft to 720 ft, a difference of 120 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 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 61×. 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, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 8 mi of the line.
Shale. Age: Late Pennsylvanian, 304 to 307 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.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 4 mi of the line.

A raindrop that lands in La Rose reaches the Gulf of America by way of Crow Creek, the Illinois and the Mississippi: about 1,390 river miles.
Lake on the way: Peoria Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of La Rose; river miles along the main stem, rounded.
La Rose 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 La Rose 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.
