71° on Nov. 14, 1999, the hottest reading for this week of the year since 1965. Next is 70° in 2001.
Fairview’s center stands about 140 ft above sea level. Within three miles the land runs from 0 ft to 400 ft, a difference of 400 ft: rolling country. The highest named summit within 15 miles is Larch Mountain, about 3,520 ft, 14 miles north-northeast.
Under the town center the state geologic map shows Tuffaceous sedimentary rocks and tuff (sandstone, siltstone, mudstone), from the Miocene to Pliocene, 2.6 to 23 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt, basaltic-andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 5 mi of the line.
Conglomerate. Age: Pliocene, 2.6 to 5.3 million years old. About 4 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Sandstone-mudstone. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 3 mi of the line.
Silt, sand, gravel. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 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. 4 smaller units along the line are not listed.

A raindrop that lands in Fairview reaches the Pacific Ocean by way of Fairview Creek, Columbia Slough and the Columbia: about 120 river miles.
100 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fairview; river miles along the main stem, rounded.
Fairview has a warm-summer Mediterranean climate. Summer afternoons average 81° in July; winter nights fall to about 35° in January. About 48 inches of rain fall in a normal year.
On November 14 Fairview normally reaches 52° and falls to 41°. The record high is 71°, in 1999; the record low 23°, in 1985. The most rain on this date, 1.20 in, fell in 1966.
Normals 1991–2020 and records since 1965 at Portland Troutdale Airport, here, 120 ft lower. NOAA, through RCC-ACIS.
