82° on Nov. 14, 2008, the hottest reading for this week of the year since 1894. Next is 82° in 2010.
Point Reyes Station’s center stands about 40 ft above sea level. Within three miles the land runs from 0 ft to 1,180 ft, a difference of 1,180 ft: steep hill country. The highest named summit within 15 miles is Ballou Point, about 2,080 ft, 15 miles southeast.
Under the town center the state geologic map shows Franciscan Complex, unit 1 (Coast Ranges) (sandstone, mudstone), from the Jurassic to Cretaceous, 66 to 202 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 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Melange. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 6 mi of the line.
Sandstone, mudstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 5 mi of the line.
Granodiorite, quartz-monzonite. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 3 mi of the line.
Greenstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 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.

Rain that falls on Point Reyes Station runs straight into the Pacific Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Point Reyes Station; river miles along the main stem, rounded.
Point Reyes Station has a warm-summer Mediterranean climate. Summer afternoons average 81° in July; winter nights fall to about 42° in December. About 34 inches of rain fall in a normal year.
On November 14 Point Reyes Station normally reaches 65° and falls to 46°. The record high is 82°, in 2008; the record low 30°, in 1894. The most rain on this date, 2.10 in, fell in 1953.
