−14° on Nov. 15, 1955, the coldest reading for this week of the year since 1893. Next is 0° in 1916.
Tekoa’s center stands about 2,500 ft above sea level. Within three miles the land runs from 2,480 ft to 3,700 ft, a difference of 1,220 ft: steep hill country. The highest named summit within 15 miles is Moses Mountain, about 4,950 ft, 15 miles east-southeast.
Under the town center the state geologic map shows Alluvium (silt, sand), from the Holocene, less than 12,000 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 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mixed-clastic. Age: Early Miocene to Late Miocene, 8 to 17 million years old. About 7 mi of the line.
Silt. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Basalt. Age: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 4 mi of the line.
Quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Basalt, basaltic-andesite. Age: Early Miocene to Late Miocene, 6 to 18 million years old. About 0.8 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 Tekoa reaches the Pacific Ocean by way of Little Hangman Creek, Hangman Creek, the Spokane and the Columbia: about 760 river miles.
Lake on the way: Lake Umatilla.
360 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tekoa; river miles along the main stem, rounded.
Tekoa has a dry-summer warm-summer continental climate. Summer afternoons average 86° in August; winter nights fall to about 24° in December. A normal year brings about 26 inches of snow; with the rain, that comes to about 18 inches of water.
On November 14 Tekoa normally reaches 46° and falls to 30°. The record high is 65°, in 1999; the record low −3°, in 1955. The most rain on this date, 0.78 in, fell in 1903.
Normals 1991–2020 and records since 1893 at Rosalia, 14 miles west. NOAA, through RCC-ACIS.
