70° on Nov. 11, 2022, the hottest reading for this week of the year since 1940. Next is 68° in 2025.
New Glarus’s center stands about 890 ft above sea level. Within three miles the land runs from 840 ft to 1,110 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Liberty Pole Hill, about 1,110 ft, 11 miles east.
Under the town center the state geologic map shows Ancell Group (sandstone), from the Ordovician, 445 to 487 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 53×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 15 mi of the line.
Dolostone. Age: Ordovician, 445 to 487 million years old. About 8 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 0.5 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 New Glarus reaches the Gulf of America by way of Legler School Branch, the Little Sugar, the Sugar, the Pecatonica, the Rock River and the Mississippi: about 1,680 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Glarus; river miles along the main stem, rounded.
New Glarus has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 11° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 40 inches of water.
Normals 1991–2020 and records since 1940 at Monroe Wwtp, 15 miles south, 100 ft higher. NOAA, through RCC-ACIS.
