Wolcottville’s center stands about 940 ft above sea level. Within three miles the land runs from 890 ft to 1,010 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Sand Hill, about 1,130 ft, 7 miles east.
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. Age: Devonian to Carboniferous, 324 to 422 million years old. About 12 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.

A raindrop that lands in Wolcottville reaches Lake Michigan by way of Little Elkhart Creek and the Saint Joseph: about 140 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
75 miles of the trip are on the Saint Joseph.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wolcottville; river miles along the main stem, rounded.
Wolcottville has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 17° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Wolcottville normally reaches 48° and falls to 31°. The record high is 64°, in 2009; the record low 13°, in 2018. The most rain on this date, 0.72 in, fell in 2024.
Normals 1991–2020 and records since 1989 at Garrett 1 S, 18 miles southeast. NOAA, through RCC-ACIS.
