14° on Nov. 14, 1986, the coldest reading for this week of the year since 1972. Next is 15° in 1996.
New Oxford’s center stands about 560 ft above sea level. Within three miles the land runs from 400 ft to 890 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Bear Mountain, about 1,600 ft, 15 miles west-northwest.
Under the town center the state geologic map shows New Oxford Formation (arkose), from the Triassic, 202 to 252 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone, shale. Age: Triassic, 202 to 252 million years old. About 7 mi of the line.
Arkose. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Quartzite, schist. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Age: Precambrian. About 2 mi of the line.
Shale. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in New Oxford reaches Chesapeake Bay and the Atlantic Ocean by way of South Branch Conewago Creek, Conewago Creek and the Susquehanna: about 110 river miles.
Lake on the way: Lake Aldred.
50 miles of the trip are on Conewago Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Oxford; river miles along the main stem, rounded.
New Oxford has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 New Oxford normally reaches 54° and falls to 35°. The record high is 66°, in 1973; the record low 14°, in 1986. The most rain on this date, 1.28 in, fell in 1972.
Normals 1991–2020 and records since 1972 at Biglerville, 12 miles west-northwest, 160 ft higher. NOAA, through RCC-ACIS.
