7° on Nov. 17, 1959, the coldest reading for this week of the year since 1888. Next is 10° in 1911.
Amber’s center stands about 680 ft above sea level. Within three miles the land runs from 590 ft to 750 ft, a difference of 160 ft: gently rolling country.
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 56×. 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 16 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 5 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 Amber reaches Lake Michigan by way of Burr Creek and the Lincoln: about 7 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 Amber; river miles along the main stem, rounded.
Amber has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 19° in January. About 36 inches of rain fall in a normal year.
On November 14 Amber normally reaches 47° and falls to 34°. The record high is 64°, in 1909; the record low 15°, in 1986. The most rain on this date, 1.38 in, fell in 1957.
Normals 1991–2020 and records since 1888 at Manistee 3 SE, 18 miles north. NOAA, through RCC-ACIS.
