The Moskowite Corner 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.
27° on Nov. 14, 2022, the coldest reading for this week of the year since 1970. Next is 28° in 1978.
Moskowite Corner’s center stands about 840 ft above sea level. Within three miles the land runs from 600 ft to 2,000 ft, a difference of 1,400 ft: steep hill country. The highest named summit within 15 miles is Mount Vaca, about 2,800 ft, 6 miles east-southeast.
Under the town center the state geologic map shows Lower Cretaceous marine rocks (siltstone-mudstone), from the Early Cretaceous, 113 to 145 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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone. Age: Early Cretaceous, 113 to 145 million years old. About 6 mi of the line.
Dacite. Age: Late Miocene to Late Pliocene, 3 to 7 million years old. About 6 mi of the line.
Sandstone, siltstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 3 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 million years old. About 2 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 Moskowite Corner reaches San Francisco Bay and the Pacific Ocean by way of Oak Moss Creek, South Fork Putah Creek, Prospect Slough, Cache Slough and the Sacramento: about 90 river miles.
Lake on the way: Lake Berryessa.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Moskowite Corner; river miles along the main stem, rounded.
Moskowite Corner has a hot-summer Mediterranean climate. Summer afternoons average 95° in July; winter nights fall to about 36° in January. About 28 inches of rain fall in a normal year.
On November 14 Moskowite Corner normally reaches 67° and falls to 41°. The record high is 81°, in 1995; the record low 27°, in 2022. The most rain on this date, 2.58 in, fell in 1972.
