−29° on Nov. 16, 1959, the coldest reading for this week of the year since 1896. Next is −24° in 1986.
Danvers’s center stands about 3,540 ft above sea level. Within three miles the land runs from 3,250 ft to 3,890 ft, a difference of 640 ft: hilly country. The highest named summit within 15 miles is Rocky Butte, about 4,920 ft, 11 miles east-southeast.
Under the town center the state geologic map shows Gravel, from the Late Miocene to Holocene, less than 7.2 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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, dolostone, limestone. Age: Late Cretaceous, 84 to 100 million years old. About 9 mi of the line.
Age: Late Miocene to Holocene, less than 7.2 million years old. About 8 mi of the line.
Gravel, sand, silt. Age: Pleistocene to Holocene, less than 1.8 million years old. About 2 mi of the line.
Granitic. Age: Cretaceous to Tertiary, 2.6 to 145 million years old. About 1 mi of the line.
Limestone, mudstone, sandstone. Age: Middle Jurassic to Late Jurassic, 145 to 172 million years old. About 1 mi of the line.
Mudstone, siltstone, sandstone. Age: Early Cretaceous, 100 to 133 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Danvers reaches the Gulf of America by way of the Judith, the Missouri and the Mississippi: about 3,200 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Fort Peck and Lake Sharpe.
1,170 miles of the trip are on the Mississippi.

Danvers has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 13° in January. About 17 inches of rain fall in a normal year.
On November 14 Danvers normally reaches 44° and falls to 21°. The record high is 72°, in 1999; the record low −21°, in 1955. The most rain on this date, 0.25 in, fell in 2011.
Normals 1991–2020 and records since 1896 at Lewistown Airport, 17 miles southeast, 580 ft higher. NOAA, through RCC-ACIS.
