84° on Nov. 11, 2016, the hottest reading for this week of the year since 1881. Next is 83° in 1900.
Rolling Hills’s center stands about 370 ft above sea level. Within three miles the land runs from 250 ft to 410 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Hulbert Mountain, about 1,810 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Older Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 15 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 2 mi of the line.
Sandstone. Age: Eocene, 34 to 56 million years old. About 0.7 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Rolling Hills has a hot semi-arid climate. Summer afternoons average 98° in July; winter nights fall to about 40° in December. About 11 inches of rain fall in a normal year.
On November 14 Rolling Hills normally reaches 65° and falls to 46°. The record high is 79°, in 1948; the record low 30°, in 1916. The most rain on this date, 1.35 in, fell in 1953.
