86° on Nov. 17, 2016, the hottest reading for this week of the year since 1914. Next is 82° in 1973.
Red Rock’s center stands about 920 ft above sea level. Within three miles the land runs from 880 ft to 1,020 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Wellington Formation (shale, sandstone, conglomerate), from the Permian, 252 to 299 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 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.
Shale, sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 12 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 8 mi of the line.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.

A raindrop that lands in Red Rock reaches the Gulf of America by way of Red Rock Creek, the Arkansas and the Mississippi: about 1,200 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Red Rock; river miles along the main stem, rounded.
Red Rock has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 23° in January. About 35 inches of rain fall in a normal year.
On November 14 Red Rock normally reaches 60° and falls to 36°. The record high is 81°, in 1999; the record low 11°, in 1959. The most rain on this date, 1.30 in, fell in 1993.
Normals 1991–2020 and records since 1914 at Billings, 16 miles west-northwest. NOAA, through RCC-ACIS.
