69° on Nov. 17, 1953, the hottest reading for this week of the year since 1895. Next is 68° in 1964.
Bergen’s center stands about 1,130 ft above sea level. Within three miles the land runs from 1,110 ft to 1,320 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Rib Mountain, about 1,940 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Wausau Pluton; Granite near Nine Mile Swamp, from the Mesoproterozoic, 1 to 1.6 billion years old.
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 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 10 mi of the line.
Metasedimentary, metavolcanic. Age: Paleoproterozoic, 1.9 to 1.9 billion years old. About 9 mi of the line.
Mylonite. Age: Archean to Paleoproterozoic. About 3 mi of the line.
Granodiorite, tonalite. Age: Paleoproterozoic, 1.8 to 1.8 billion years old. About 1 mi of the line.
Quartz-syenite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.9 mi of the line.

A raindrop that lands in Bergen reaches the Gulf of America by way of Lake Du Bay, the Wisconsin and the Mississippi: about 1,860 river miles.
Lakes on the way: Petenwell Lake, Lake Wisconsin, Lake Du Bay and Wisconsin River Flowage 4964.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bergen; river miles along the main stem, rounded.
Bergen has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 7° in January. A normal year brings about 64 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Bergen normally reaches 41° and falls to 26°. The record high is 64°, in 1990; the record low −2°, in 1916. The most rain on this date, 0.75 in, fell in 1902.
Normals 1991–2020 and records since 1895 from the Wausau Area threaded record (Wausau Asos, 15 miles north-northeast). NOAA, through RCC-ACIS.
