Mentor’s center stands about 1,040 ft above sea level. Within three miles the land runs from 1,000 ft to 1,250 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is South Mound, about 1,450 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 23 mi of the line.
Gneiss. Age: Mesoarchean to Neoarchean, 2.5 to 2.9 billion years old. About 0.9 mi of the line.

A raindrop that lands in Mentor reaches the Gulf of America by way of Fivemile Creek, Wedges Creek, the Black River, the Dodge Chute and the Mississippi: about 1,780 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mentor; river miles along the main stem, rounded.
Mentor has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 5° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Mentor normally reaches 43° and falls to 25°. The record high is 70°, in 1999; the record low −7°, in 1916. The most rain on this date, 1.26 in, fell in 1902.
Normals 1991–2020 and records since 1893 at Neillsville 3 ESE, 16 miles east. NOAA, through RCC-ACIS.
