88° on Nov. 17, 1932, the hottest reading for this week of the year since 1893. Next is 85° in 1930.
Talmage’s center stands about 640 ft above sea level. Within three miles the land runs from 560 ft to 2,340 ft, a difference of 1,780 ft: steep hill country. The highest named summit within 15 miles is Red Mountain, about 3,370 ft, 6 miles southeast.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, 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 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, mudstone. Age: Jurassic to Cretaceous, 66 to 202 million years old. About 11 mi of the line.
Sandstone, mudstone. Age: Late Cretaceous to Pliocene, 2.6 to 100 million years old. About 10 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 0.8 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.5 mi of the line.

A raindrop that lands in Talmage reaches the Pacific Ocean by way of Mill Creek and the Russian: about 95 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Talmage; river miles along the main stem, rounded.
Talmage has a hot-summer Mediterranean climate. Summer afternoons average 94° in July; winter nights fall to about 36° in December. About 35 inches of rain fall in a normal year.
On November 14 Talmage normally reaches 65° and falls to 40°. The record high is 79°, in 2008; the record low 20°, in 1916. The most rain on this date, 1.91 in, fell in 1903.
