75° on Nov. 11, 2020, the hottest reading for this week of the year since 1895. Next is 75° in 2022.
Pinconning’s center stands about 600 ft above sea level. Within three miles the land runs from 570 ft to 650 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Saginaw Formation (sandstone, shale), from the Carboniferous, 299 to 324 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.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Pinconning reaches Lake Huron by way of the Pinconning: about 3 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 Pinconning; river miles along the main stem, rounded.
Pinconning has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 14° in January. About 31 inches of rain fall in a normal year.
