Under the town center the state geologic map shows Lexington Limestone, from the Middle Ordovician, 459 to 471 million years old.
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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 23 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.

A raindrop that lands in Keene reaches the Gulf of America by way of Cave Spring Creek, Clear Creek, the Kentucky, the Ohio and the Mississippi: about 1,510 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Keene; river miles along the main stem, rounded.
Keene has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 25° in January. A normal year brings about 14 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Keene normally reaches 56° and falls to 37°. The record high is 77°, in 1971; the record low 15°, in 1986. The most rain on this date, 1.52 in, fell in 1915.
