9° on Nov. 16, 1967, the coldest reading for this week of the year since 1951. Next is 12° in 1959.
Union’s center stands about 1,010 ft above sea level. Within three miles the land runs from 810 ft to 1,450 ft, a difference of 640 ft: hilly country. The highest named summit within 15 miles is Cork Hill, about 1,940 ft, 10 miles south-southwest.
Under the town center the state geologic map shows Upper Walton Formation (shale, sandstone, conglomerate), 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 18×. 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, sandstone, conglomerate. Age: Late Devonian, 359 to 384 million years old. About 12 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million 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.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Union reaches Chesapeake Bay and the Atlantic Ocean by way of Patterson Creek and the Susquehanna: about 330 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Union; river miles along the main stem, rounded.
Union 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 Union 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), 6 miles north-northeast, 580 ft higher). NOAA, through RCC-ACIS.
