5.39 inches of rain fell in two days, the most for this week of the year since records began in 1887. The next wettest, 5.30 inches, fell in 2015.
Naselle’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 1,050 ft, a difference of 1,050 ft: steep hill country. The highest named summit within 15 miles is Elk Mountain, about 1,500 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Miocene marine rocks (sandstone, siltstone), from the Miocene, 5.3 to 23 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 10×. 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, siltstone. Age: Miocene, 5.3 to 23 million years old. About 5 mi of the line.
Sandstone. Age: Early Eocene to Middle Eocene, 38 to 56 million years old. About 5 mi of the line.
Sandstone, siltstone. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 4 mi of the line.
Basalt. Age: Early Paleocene to Middle Eocene, 40 to 64 million years old. About 3 mi of the line.
Basalt, basaltic-andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 2 mi of the line.
Quartz-monzonite, granite, basalt. Age: Eocene to Early Pliocene, 3.6 to 56 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.

A raindrop that lands in Naselle reaches the Pacific Ocean by way of the Naselle: about 15 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Naselle; river miles along the main stem, rounded.
Naselle has a warm-summer Mediterranean climate. Summer afternoons average 69° in August; winter nights fall to about 37° in February. About 70 inches of rain fall in a normal year.
On November 14 Naselle normally reaches 54° and falls to 40°. The record high is 64°, in 2001; the record low 15°, in 1955. The most rain on this date, 2.78 in, fell in 2015.
Normals 1991–2020 and records since 1887 from the Astoria Area threaded record (Astoria Airport (Port Of), 15 miles south-southwest). NOAA, through RCC-ACIS.
