The Hood River 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.
22° on Nov. 15, 1909, the coldest reading for this week of the year since 1894. Next is 22° in 1911.
Hood River’s center stands about 290 ft above sea level. Within three miles the land runs from 70 ft to 1,500 ft, a difference of 1,430 ft: steep hill country. The highest named summit within 15 miles is Mount Defiance, about 4,950 ft, 10 miles west-southwest.
Under the town center the state geologic map shows Lacustrine and fluvial sedimentary rocks (clay, silt, sand), from the Pleistocene, less than 2.6 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 4×. 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: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 9 mi of the line.
Basaltic-andesite, basalt. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Basaltic-andesite, basalt. Age: Early Pliocene to Pleistocene, 1.2 to 3.9 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.
Basalt. Age: Early Miocene to Middle Miocene, 12 to 23 million years old. About 1 mi of the line.
Basalt. Age: Early Pliocene to Holocene, less than 5.3 million years old. About 0.7 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 Hood River reaches the Pacific Ocean by way of the Columbia: about 160 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hood River; river miles along the main stem, rounded.
Hood River has a cold desert climate. Summer afternoons average 82° in August; winter nights fall to about 33° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Hood River normally reaches 51° and falls to 39°. The record high is 65°, in 1906; the record low 25°, in 1916. The most rain on this date, 2.77 in, fell in 1896.
Normals 1991–2020 and records since 1894 at Cascade Locks, 17 miles west, 150 ft lower. NOAA, through RCC-ACIS.
