14° on Nov. 17, 1996, the coldest reading for this week of the year since 1991. Next is 20° in 1995.
Voorhees’s center stands about 140 ft above sea level. Within three miles the land runs from 60 ft to 200 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Lower Member of the Kirkwood Formation (clay, sand), from the Early Miocene, 16 to 23 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Middle Miocene, 12 to 14 million years old. About 12 mi of the line.
Sand, clay. Age: Late Cretaceous, 94 to 100 million years old. About 2 mi of the line.
Clay, sand. Age: Early Miocene, 16 to 23 million years old. About 2 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
Clay, silt. Age: Late Cretaceous, 72 to 84 million years old. About 1 mi of the line.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 6 smaller units along the line are not listed.
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 Voorhees reaches Delaware Bay and the Atlantic Ocean by way of Millard Creek, the Cooper and the Delaware: about 85 river miles.
70 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Voorhees; river miles along the main stem, rounded.
Voorhees has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 25° in January. About 48 inches of rain fall in a normal year.
On November 14 Voorhees normally reaches 55° and falls to 37°. The record high is 78°, in 1993; the record low 20°, in 2019. The most rain on this date, 0.91 in, fell in 2006.
Normals 1991–2020 and records since 1991 at Pennsauken 1 N, 9 miles north-northwest. NOAA, through RCC-ACIS.
