87° on Nov. 15, 1941, the hottest reading for this week of the year since 1895. Next is 84° in 2016.
Marienthal’s center stands about 3,220 ft above sea level. Within three miles the land runs from 3,170 ft to 3,240 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Pleistocene to Holocene, less than 2.6 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 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 24 mi of the line.
Arkose. Age: Miocene, 5.3 to 23 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Marienthal has a cold semi-arid climate. Summer afternoons average 93° in July; winter nights fall to about 16° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Marienthal normally reaches 56° and falls to 26°. The record high is 83°, in 1999; the record low −2°, in 1916. The most rain on this date, 0.45 in, fell in 1926.
Normals 1991–2020 and records since 1895 at Scott City, 16 miles east, 250 ft lower. NOAA, through RCC-ACIS.
