63° on Nov. 15, 1953, the hottest reading for this week of the year since 1899. Next is 59° in 2007.
Orient’s center stands about 1,470 ft above sea level. Within three miles the land runs from 1,390 ft to 3,920 ft, a difference of 2,530 ft: mountain country. The highest named summit within 15 miles is Lambert Mountain, about 6,510 ft, 15 miles southwest.
Under the town center the state geologic map shows Glacial drift, undivided (sand, gravel), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 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.
Granite. Age: Precambrian to Eocene. About 7 mi of the line.
Gneiss. Age: Paleozoic to Mesozoic, 66 to 542 million years old. About 6 mi of the line.
Andesite, dacite. Age: Eocene to Oligocene, 23 to 56 million years old. About 4 mi of the line.
Latite, andesite. Age: Early Jurassic to Middle Jurassic, 164 to 192 million years old. About 4 mi of the line.
Sand, gravel. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Metasedimentary. Age: Devonian to Permian, 273 to 422 million 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.

A raindrop that lands in Orient reaches the Pacific Ocean by way of the Columbia: about 710 river miles.
Lake on the way: Lake Umatilla.
420 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Orient; river miles along the main stem, rounded.
Orient has a dry-summer warm-summer continental climate. Summer afternoons average 86° in August; winter nights fall to about 20° in January. A normal year brings about 47 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Orient normally reaches 41° and falls to 28°. The record high is 58°, in 2016; the record low 8°, in 1955. The most rain on this date, 0.85 in, fell in 1966.
Normals 1991–2020 and records since 1899 at Northport, 17 miles east. NOAA, through RCC-ACIS.
