The Centerville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
88° on Nov. 13, 1995, the hottest reading for this week of the year since 1893. Next is 87° in 1933.
Centerville’s center stands about 850 ft above sea level. Within three miles the land runs from 540 ft to 1,950 ft, a difference of 1,410 ft: steep hill country. The highest named summit within 15 miles is Paradise Peak, about 6,310 ft, 15 miles west.
Under the town center the state geologic map shows Paleozoic metavolcanic rocks, unit 1 (Eastern Klamath Mountains) (mafic-volcanic), from the Permian, 252 to 299 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Diorite. Age: Jurassic to Early Cretaceous, 100 to 202 million years old. About 6 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 5 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 5 mi of the line.
Mafic-volcanic. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Granodiorite, trondhjemite. Age: Early Devonian to Late Devonian, 364 to 400 million years old. About 4 mi of the line.
Gneiss, amphibolite. Age: Devonian, 359 to 422 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Centerville reaches San Francisco Bay and the Pacific Ocean by way of Olney Creek and the Sacramento: about 290 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Centerville; river miles along the main stem, rounded.
Centerville has a hot-summer Mediterranean climate. Summer afternoons average 100° in July; winter nights fall to about 37° in December. About 34 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Centerville normally reaches 65° and falls to 42°. The record high is 87°, in 1933; the record low 23°, in 1985. The most rain on this date, 2.32 in, fell in 1934.
