−4° on Nov. 15, 2019, the coldest reading for this week of the year since 1891. Next is −3° in 1943.
Blue Lake’s center stands about 1,390 ft above sea level. Within three miles the land runs from 1,180 ft to 1,440 ft, a difference of 260 ft: rolling country.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. 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: Carboniferous, 324 to 359 million years old. About 24 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 Blue Lake reaches Lake Michigan by way of Goose Creek and the Manistee: about 170 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 Blue Lake; river miles along the main stem, rounded.
Blue Lake has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 9° in February. A normal year brings about 88 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Blue Lake normally reaches 43° and falls to 27°. The record high is 65°, in 1953; the record low 3°, in 1940. The most rain on this date, 0.76 in, fell in 1951.
Normals 1991–2020 and records since 1891 at Grayling, 15 miles southeast, 240 ft lower. NOAA, through RCC-ACIS.
