68° on Nov. 17, 1953, the hottest reading for this week of the year since 1892. Next is 68° in 1999.
Macville’s center stands about 1,280 ft above sea level. Within three miles the land runs from 1,260 ft to 1,370 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Quadna Mountain, about 1,620 ft, 5 miles north-northeast.
Under the town center the state geologic map shows Slate and graywacke (slate, graywacke), from the Paleoproterozoic, 1.6 to 2 billion 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 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Slate, graywacke. Age: Paleoproterozoic, 1.6 to 2 billion years old. About 14 mi of the line.
Conglomerate, lignite, sandstone. Age: Late Cretaceous, 94 to 100 million years old. About 10 mi of the line.

A raindrop that lands in Macville reaches the Gulf of America by way of the Willow, Pokegama Creek and the Mississippi: about 2,120 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 Macville; river miles along the main stem, rounded.
Macville has a cold desert climate. Summer afternoons average 78° in July; winter nights fall to about −2° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Macville normally reaches 38° and falls to 23°. The record high is 64°, in 2005; the record low −7°, in 1919. The most rain on this date, 1.24 in, fell in 1909.
Normals 1991–2020 and records since 1892 at Sandy Lake Dam Libby, 16 miles east-southeast. NOAA, through RCC-ACIS.
