79° on Nov. 17, 1958, the hottest reading for this week of the year since 1926. Next is 79° in 1993.
Williamstown’s center stands about 640 ft above sea level. Within three miles the land runs from 580 ft to 900 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Buzzard Rocks, about 1,270 ft, 14 miles southeast.
Under the town center the state geologic map shows Quaternary Alluvium (fine-detrital, coarse-detrital), from the Quaternary, less than 2.6 million years old.
The section below crosses 3 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.
Mudstone, shale, siltstone. Age: Carboniferous to Permian, 252 to 324 million years old. About 17 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.

A raindrop that lands in Williamstown reaches the Gulf of America by way of Williams Creek, the Ohio and the Mississippi: about 1,770 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 Williamstown; river miles along the main stem, rounded.
Williamstown has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 24° in January. About 42 inches of rain fall in a normal year.
On November 14 Williamstown normally reaches 55° and falls to 35°. The record high is 79°, in 1993; the record low 11°, in 1986. The most rain on this date, 1.25 in, fell in 2007.
