83° on Nov. 15, 2025, the hottest reading for this week of the year since 1919. Next is 81° in 1999.
Max’s center stands about 2,910 ft above sea level. Within three miles the land runs from 2,860 ft to 3,190 ft, a difference of 330 ft: rolling country.
Under the town center the state geologic map shows Pierre Shale, from the Late Cretaceous, 66 to 100 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 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 16 mi of the line.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 4 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 Max reaches the Gulf of America by way of the Republican, the Kansas, the Missouri and the Mississippi: about 2,100 river miles.
Lakes on the way: Harlan County Lake and Swanson Lake.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Max; river miles along the main stem, rounded.
Max has a hot-summer humid continental climate. Summer afternoons average 91° in July; winter nights fall to about 15° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Max normally reaches 54° and falls to 26°. The record high is 81°, in 1999; the record low −3°, in 1959. The most rain on this date, 0.12 in, fell in 1993.
Normals 1991–2020 and records since 1919 at Trenton Dam 1 N, 19 miles east-northeast. NOAA, through RCC-ACIS.
