72° on Nov. 12, 1999, the hottest reading for this week of the year since 1908. Next is 70° in 1934.
Shoshone’s center stands about 3,970 ft above sea level. Within three miles the land runs from 3,890 ft to 4,100 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Kinzie Butte, about 4,920 ft, 11 miles north-northeast.
Under the town center the state geologic map shows Alluvial deposits (gravel, sand, silt), from the Quaternary, less than 2.6 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. 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. Age: Late Pliocene to Pleistocene, less than 3 million years old. About 20 mi of the line.
Gravel, sand, silt. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sand. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Shoshone reaches the Pacific Ocean by way of the Little Wood, the Malad, the Snake and the Columbia: about 920 river miles.
Lakes on the way: Lake Umatilla, Brownlee Reservoir, Cove Arm Lake and Hells Canyon Reservoir.
240 miles of the trip are on the Snake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shoshone; river miles along the main stem, rounded.
Shoshone has a cold semi-arid climate. Summer afternoons average 94° in July; winter nights fall to about 23° in January. About 10 inches of rain fall in a normal year.
On November 14 Shoshone normally reaches 50° and falls to 32°. The record high is 68°, in 2016; the record low 3°, in 1916. The most rain on this date, 0.71 in, fell in 2006.
