70° on Nov. 13, 1999, the hottest reading for this week of the year since 1892. Next is 68° in 1930.
Adair Village’s center stands about 320 ft above sea level. Within three miles the land runs from 200 ft to 1,170 ft, a difference of 970 ft: steep hill country. The highest named summit within 15 miles is Forest Peak, about 1,950 ft, 5 miles west.
Under the town center the state geologic map shows Terrace, pediment, and lag gravels (gravel, boulders, clay), 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 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.
Basalt. Age: Paleocene to Middle Eocene, 38 to 66 million years old. About 12 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Mudstone. Age: Middle Eocene to Late Eocene, 34 to 48 million years old. About 3 mi of the line.
Gravel, boulders, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.

A raindrop that lands in Adair Village reaches the Pacific Ocean by way of Bowers Slough, the Willamette and the Columbia: about 230 river miles.
Lake on the way: Willamette Falls Hydroelectric Power Reservoir.
100 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Adair Village; river miles along the main stem, rounded.
Adair Village has a warm-summer Mediterranean climate. Summer afternoons average 84° in July; winter nights fall to about 35° in December. About 40 inches of rain fall in a normal year.
On November 14 Adair Village normally reaches 54° and falls to 39°. The record high is 68°, in 2001; the record low 12°, in 1955. The most rain on this date, 3.00 in, fell in 1896.
