The Millville 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.
Millville’s center stands about 510 ft above sea level. Within three miles the land runs from 450 ft to 820 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Blue Mountain, about 3,090 ft, 14 miles east.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, 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 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 10 mi of the line.
Sandstone, siltstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Andesite. Age: Late Oligocene to Pleistocene, 2 to 24 million years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Millville reaches San Francisco Bay and the Pacific Ocean by way of Cow Creek and the Sacramento: about 290 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Millville; river miles along the main stem, rounded.
Millville 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 Millville 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.
