Gardner’s center stands about 590 ft above sea level. Within three miles the land runs from 560 ft to 600 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Carbondale Formation (shale, sandstone, coal), from the Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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 23 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 1 mi of the line.

A raindrop that lands in Gardner reaches the Gulf of America by way of the Mazon, the Illinois and the Mississippi: about 1,480 river miles.
Lake on the way: Peoria Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gardner; river miles along the main stem, rounded.
Gardner has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Gardner normally reaches 49° and falls to 30°. The record high is 74°, in 1999; the record low 8°, in 1996. The most rain on this date, 0.80 in, fell in 1991.
Normals 1991–2020 and records since 1990 at Dwight Wwtp, 8 miles southwest. NOAA, through RCC-ACIS.
