77° on Nov. 13, 1999, the hottest reading for this week of the year since 1935. Next is 75° in 1939.
Marshall’s center stands about 1,170 ft above sea level. Within three miles the land runs from 1,120 ft to 1,200 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated (conglomerate, sandstone, mudstone), from the Late Cretaceous, 72 to 100 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 22 mi of the line.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion 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.

A raindrop that lands in Marshall reaches the Gulf of America by way of the Redwood, the Minnesota and the Mississippi: about 2,100 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marshall; river miles along the main stem, rounded.
Marshall has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 4° in January. A normal year brings about 44 inches of snow; with the rain, that comes to about 29 inches of water.
On November 14 Marshall normally reaches 44° and falls to 23°. The record high is 70°, in 1953; the record low −8°, in 1940. The most rain on this date, 0.33 in, fell in 1983.
