64° on Nov. 16, 1923, the hottest reading for this week of the year since 1916. Next is 63° in 1999.
Stanley’s center stands about 6,370 ft above sea level. Within three miles the land runs from 6,210 ft to 7,620 ft, a difference of 1,410 ft: steep hill country. The highest named summit within 15 miles is Mount Cramer, about 10,630 ft, 14 miles south.
Under the town center the state geologic map shows Glacial deposits (coarse-detrital, fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite, granite. Age: Early Cretaceous to Late Cretaceous, 67 to 107 million years old. About 8 mi of the line.
Tonalite, granodiorite, quartz-diorite. Age: Late Cretaceous, 70 to 100 million years old. About 8 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Granodiorite, quartz-monzodiorite, granite. Age: Early Eocene to Middle Eocene, 43 to 49 million years old. About 2 mi of the line.

A raindrop that lands in Stanley reaches the Pacific Ocean by way of Valley Creek, the Salmon, the Snake and the Columbia: about 890 river miles.
Lake on the way: Lake Umatilla.
380 miles of the trip are on the Salmon.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stanley; river miles along the main stem, rounded.
Stanley has a dry-summer warm-summer continental climate. Summer afternoons average 80° in July; winter nights fall to about 4° in January. About 18 inches of rain fall in a normal year.
On November 14 Stanley normally reaches 40° and falls to 14°. The record high is 60°, in 1923; the record low −9°, in 1982. The most rain on this date, 0.48 in, fell in 2014.
Normals 1991–2020 and records since 1916 from the Stanley Area threaded record (Stanley Ranger Station, 3 miles south, 120 ft higher). NOAA, through RCC-ACIS.
