9° on Nov. 16, 1967, the coldest reading for this week of the year since 1951. Next is 12° in 1959.
Triangle’s center stands about 1,080 ft above sea level. Within three miles the land runs from 1,020 ft to 1,540 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Bobell Hill, about 1,820 ft, 11 miles east-southeast.
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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. 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 14 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 9 mi of the line.
Shale, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.

A raindrop that lands in Triangle reaches Chesapeake Bay and the Atlantic Ocean by way of the Tioughnioga, the Chenango and the Susquehanna: about 360 river miles.
Lake on the way: Lake Aldred.
290 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Triangle; river miles along the main stem, rounded.
Triangle has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 15° in January. A normal year brings about 86 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Triangle normally reaches 46° and falls to 31°. The record high is 66°, in 1989; the record low 12°, in 1986. The most rain on this date, 1.54 in, fell in 1972.
Normals 1991–2020 and records since 1951 from the Binghamton Area threaded record (Binghamton (Greater Ap), 11 miles south-southwest, 510 ft higher). NOAA, through RCC-ACIS.
