70° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 68° in 1989.
Thurman’s center stands about 1,330 ft above sea level. Within three miles the land runs from 1,000 ft to 2,890 ft, a difference of 1,890 ft: steep hill country. The highest named summit within 15 miles is Gore Mountain, about 3,600 ft, 12 miles northwest.
Under the town center the state geologic map shows Undivided metasedimentary rock and related migmatite (metasedimentary, migmatite), from the Mesoproterozoic, 1 to 1.6 billion 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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Metaanorthosite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Gneiss, metasedimentary. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 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 Thurman reaches New York Harbor and the Atlantic Ocean by way of Stony Creek and the Hudson: about 250 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Thurman; river miles along the main stem, rounded.
Thurman has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 12° in January. A normal year brings about 60 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Thurman normally reaches 46° and falls to 31°. The record high is 68°, in 1989; the record low 12°, in 2019. The most rain on this date, 0.78 in, fell in 1988.
Normals 1991–2020 and records since 1948 at Conklingville Dam, 15 miles south, 520 ft lower. NOAA, through RCC-ACIS.
