77° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 75° in 1902.
Marquette’s center stands about 630 ft above sea level. Within three miles the land runs from 610 ft to 1,090 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Mondell Hill, about 1,150 ft, 3 miles east.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. 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: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 4 mi of the line.
Dolostone, sandstone. Age: Early Ordovician to Late Ordovician, 454 to 487 million years old. About 4 mi of the line.
Shale, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 4 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Marquette reaches the Gulf of America by way of Bloody Run and the Mississippi: about 1,610 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marquette; river miles along the main stem, rounded.
Marquette has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 10° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Marquette normally reaches 47° and falls to 29°. The record high is 77°, in 1999; the record low 4°, in 1916. The most rain on this date, 1.05 in, fell in 1902.
Normals 1991–2020 and records since 1893 at Prairie Du Chien, 2 miles east-northeast. NOAA, through RCC-ACIS.
