The North Robinson plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
78° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 74° in 1893.
North Robinson’s center stands about 1,070 ft above sea level. Within three miles the land runs from 1,030 ft to 1,150 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Ralston Knob, about 1,420 ft, 12 miles east.
Under the town center the state geologic map shows Berea Sandstone and Bedford Shale, Undivided (sandstone, shale), from the Devonian, 359 to 422 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 40×. 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, black-shale. Age: Devonian, 359 to 422 million years old. About 8 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 5 mi of the line.

Limestone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Shale. Age: Devonian, 359 to 422 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in North Robinson reaches Lake Erie by way of the Sandusky: about 120 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.

North Robinson has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 20° 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 North Robinson normally reaches 52° and falls to 35°. The record high is 72°, in 1909; the record low 6°, in 2019. The most rain on this date, 1.15 in, fell in 1972.
