73° on Nov. 17, 2016, the hottest reading for this week of the year since 1914. Next is 72° in 1952.
Dunlap’s center stands about 780 ft above sea level. Within three miles the land runs from 750 ft to 880 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Buzzard Hill, about 1,050 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Ellsworth Shale, from the Devonian to Carboniferous, 324 to 422 million years old.
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 24 mi of the line.

A raindrop that lands in Dunlap reaches Lake Michigan by way of Yellow Creek and the Saint Joseph: about 80 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dunlap; river miles along the main stem, rounded.
Dunlap has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 18° in January. A normal year brings about 45 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Dunlap normally reaches 49° and falls to 33°. The record high is 69°, in 1956; the record low 10°, in 1940. The most rain on this date, 1.13 in, fell in 1957.
Normals 1991–2020 and records since 1914 at Goshen 3 SW, 6 miles south-southeast. NOAA, through RCC-ACIS.
