68° on Nov. 12, 1999, the hottest reading for this week of the year since 1897. Next is 63° in 1937.
Worley’s center stands about 2,650 ft above sea level. Within three miles the land runs from 2,580 ft to 3,650 ft, a difference of 1,070 ft: steep hill country. The highest named summit within 15 miles is Cable Peak, about 4,950 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Sedimentary rocks associated with flood basalts (mixed-clastic), from the Early Miocene to Late Miocene, 8 to 17 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 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, basaltic-andesite. Age: Early Miocene to Late Miocene, 6 to 18 million years old. About 7 mi of the line.
Mixed-clastic. Age: Early Miocene to Late Miocene, 8 to 17 million years old. About 5 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Metasiltstone, quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.6 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 Worley reaches the Pacific Ocean by way of North Fork Rock Creek, Rock Creek, Hangman Creek, the Spokane and the Columbia: about 750 river miles.
Lake on the way: Lake Umatilla.
360 miles of the trip are on the Columbia.

Worley has a dry-summer warm-summer continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in January. A normal year brings about 56 inches of snow; with the rain, that comes to about 31 inches of water.
On November 14 Worley normally reaches 44° and falls to 30°. The record high is 62°, in 1899; the record low 4°, in 1955. The most rain on this date, 1.50 in, fell in 1897.
Normals 1991–2020 and records since 1897 at Saint Maries, 17 miles east-southeast, 500 ft lower. NOAA, through RCC-ACIS.
