73° on Nov. 11, 2020, the hottest reading for this week of the year since 1880. Next is 71° in 1909.
Barton Hills’s center stands about 990 ft above sea level. Within three miles the land runs from 780 ft to 1,000 ft, a difference of 220 ft: rolling country.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 58×. 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 18 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 0.9 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 0.7 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.6 mi of the line.

A raindrop that lands in Barton Hills reaches Lake Erie by way of the Huron: about 55 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 Barton Hills; river miles along the main stem, rounded.
Barton Hills has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 16° in January. A normal year brings about 61 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Barton Hills normally reaches 49° and falls to 31°. The record high is 71°, in 1909; the record low 11°, in 2018. The most rain on this date, 1.31 in, fell in 1957.
Normals 1991–2020 and records since 1880 at Ann Arbor U Of Mich, 6 miles east-southeast, 180 ft lower. NOAA, through RCC-ACIS.
