74° on Nov. 17, 1953, the hottest reading for this week of the year since 1892. Next is 66° in 1923.
Halstad’s center stands about 870 ft above sea level. Within three miles the land runs from 840 ft to 880 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Gabbro, peridotite, pyroxenite, lamprophyre, and metamorphic equivalents, from the Neoarchean, 2.5 to 2.8 billion years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, shale. Age: Early Cretaceous, 100 to 145 million years old. About 7 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 6 mi of the line.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Gabbro, peridotite, pyroxenite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Plutonic. Age: Archean. About 1 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 Halstad reaches Hudson Bay by way of the Red River of the North and the Nelson: about 1,020 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Halstad; river miles along the main stem, rounded.
Halstad has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −4° in January. About 25 inches of rain fall in a normal year.
On November 14 Halstad normally reaches 37° and falls to 19°. The record high is 67°, in 1953; the record low −20°, in 1919. The most rain on this date, 0.46 in, fell in 1971.
Normals 1991–2020 and records since 1892 at Ada, 15 miles east-southeast. NOAA, through RCC-ACIS.
