14° on Nov. 14, 1986, the coldest reading for this week of the year since 1972. Next is 15° in 1996.
Cooke’s center stands about 1,320 ft above sea level. Within three miles the land runs from 830 ft to 1,750 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Methodist Hill, about 2,070 ft, 10 miles west-southwest.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 8 mi of the line.
Age: Precambrian. About 7 mi of the line.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 6 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Phyllite, schist. Age: Cambrian, 487 to 542 million years old. About 0.3 mi of the line.

A raindrop that lands in Cooke reaches Chesapeake Bay and the Atlantic Ocean by way of Toms Run, Mountain Creek, Yellow Breeches Creek and the Susquehanna: about 120 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cooke; river miles along the main stem, rounded.
Cooke has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Cooke normally reaches 54° and falls to 35°. The record high is 66°, in 1973; the record low 14°, in 1986. The most rain on this date, 1.28 in, fell in 1972.
Normals 1991–2020 and records since 1972 at Biglerville, 8 miles south-southeast, 600 ft lower. NOAA, through RCC-ACIS.
