14° on Nov. 17, 1959, the coldest reading for this week of the year since 1938. Next is 14° in 2019.
Montour’s center stands about 710 ft above sea level. Within three miles the land runs from 440 ft to 1,640 ft, a difference of 1,200 ft: steep hill country. The highest named summit within 15 miles is Connecticut Hill, about 2,140 ft, 9 miles east-northeast.
Under the town center the state geologic map shows Genesee Group (shale), from the Late Devonian, 359 to 384 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 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.

A raindrop that lands in Montour reaches Lake Ontario by way of L'Hommedieu Creek, the Seneca and the Oswego: about 130 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lakes on the way: Seneca Lake and Cayuga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Montour; river miles along the main stem, rounded.
Montour has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 16° in January. About 32 inches of rain fall in a normal year.
On November 14 Montour normally reaches 50° and falls to 30°. The record high is 69°, in 1945; the record low 17°, in 2014. The most rain on this date, 0.40 in, fell in 2011.
Normals 1991–2020 and records since 1938 at Elmira Corning Regional Airport, 13 miles south-southwest, 230 ft higher. NOAA, through RCC-ACIS.
