70° on Nov. 14, 2021, the hottest reading for this week of the year since 1941. Next is 66° in 1976.
George’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,200 ft to 1,290 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Cape Horn, about 2,220 ft, 13 miles northwest.
Under the town center the state geologic map shows Younger glacial drift (fine-detrital, coarse-detrital), from the Pleistocene, 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 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 13 mi of the line.
Silt. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Basalt. Age: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 5 mi of the line.
Sandstone, clay, volcanic. Age: Pleistocene, less than 2.6 million years old. About 0.8 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 0.3 mi of the line.

A raindrop that lands in George reaches the Pacific Ocean by way of the Frenchman Hills Wasteway, Lower Crab Creek and the Columbia: about 490 river miles.
Lakes on the way: Lake Umatilla and Potholes Reservoir.
210 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of George; river miles along the main stem, rounded.
George has a cold semi-arid climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 8 inches of rain fall in a normal year.
On November 14 George normally reaches 47° and falls to 30°. The record high is 70°, in 2021; the record low 0°, in 1955. The most rain on this date, 0.46 in, fell in 1981.
Normals 1991–2020 and records since 1941 at Quincy, 10 miles north. NOAA, through RCC-ACIS.
