Highland’s center stands about 620 ft above sea level. Within three miles the land runs from 390 ft to 760 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Britton Hill, about 820 ft, 10 miles north-northeast.
Under the town center the state geologic map shows Cotter and Jefferson City Dolomites (dolostone), from the Early Ordovician, 471 to 487 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 36×. 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 22 mi of the line.

A raindrop that lands in Highland reaches the Gulf of America by way of Little Otter Creek, the Spring, the Black River, the White River and the Mississippi: about 990 river miles.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Highland; river miles along the main stem, rounded.
Highland has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 26° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Highland normally reaches 59° and falls to 38°. The record high is 78°, in 1999; the record low 11°, in 2019. The most rain on this date, 0.85 in, fell in 1915.
