67° on Nov. 15, 1999, the hottest reading for this week of the year since 1956. Next is 65° in 2001.
Jump River’s center stands about 1,190 ft above sea level. Within three miles the land runs from 1,160 ft to 1,330 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Mafic to felsic metavolcanic rocks, from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 8 mi of the line.
Granite, tonalite, gneiss. Age: Paleoproterozoic, 1.8 to 1.9 billion years old. About 6 mi of the line.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Jump River reaches the Gulf of America by way of the Jump, the Chippewa and the Mississippi: about 1,870 river miles.
Lakes on the way: Lake Wissota and Holcombe Flowage.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jump River; river miles along the main stem, rounded.
Jump River has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 2° in January. About 34 inches of rain fall in a normal year.
On November 14 Jump River normally reaches 40° and falls to 25°. The record high is 64°, in 1990; the record low −1°, in 1996. The most rain on this date, 0.13 in, fell in 2000.
Normals 1991–2020 and records since 1956 at Big Falls Hydro, 16 miles north-northwest. NOAA, through RCC-ACIS.
