76° on Nov. 15, 1993, the hottest reading for this week of the year since 1925. Next is 75° in 2020.
Danvers’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 210 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Holt Hill, about 450 ft, 10 miles west-northwest.
The section below crosses 10 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.
Tonalite, diorite. Age: Silurian, 425 to 435 million years old. About 5 mi of the line.
Diorite, gabbro. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Granite, pegmatite. Age: Ordovician to Silurian, 422 to 487 million years old. About 2 mi of the line.
Alkali-granite, quartz-syenite. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 2 mi of the line.
Granite, granodiorite. Age: Silurian, 422 to 445 million years old. About 0.8 mi of the line.
Granodiorite. Age: Neoproterozoic, 542 to 1,000 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. 4 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Danvers reaches the Atlantic Ocean by way of Beaver Brook: about 5 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Danvers; river miles along the main stem, rounded.
Danvers has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Danvers normally reaches 51° and falls to 32°. The record high is 70°, in 2016; the record low 13°, in 2019. The most rain on this date, 3.27 in, fell in 2009.
Normals 1991–2020 and records since 1925 at Middleton, 5 miles west-northwest. NOAA, through RCC-ACIS.
