79° on Nov. 15, 1993, the hottest reading for this week of the year since 1940. Next is 78° in 2005.
Ashland’s center stands about 80 ft above sea level. Within three miles the land runs from 40 ft to 150 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Georges Hill, about 250 ft, 14 miles northwest.
Under the town center the state geologic map shows Navesink Formation (sand), from the Late Cretaceous, 66 to 72 million years old.
The section below crosses 13 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 7 mi of the line.
Clay, sand. Age: Early Miocene, 16 to 23 million years old. About 4 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 2 mi of the line.
Sand, clay. Age: Late Cretaceous, 94 to 100 million years old. About 2 mi of the line.
Sand. Age: Early Paleocene, 62 to 66 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. 7 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 Ashland reaches Delaware Bay and the Atlantic Ocean by way of the Cooper and the Delaware: about 80 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ashland; river miles along the main stem, rounded.
Ashland has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Ashland normally reaches 57° and falls to 42°. The record high is 74°, in 1955; the record low 26°, in 1986. The most rain on this date, 1.09 in, fell in 1940.
Normals 1991–2020 and records since 1940 from the Philadelphia Center City Area threaded record (Philadelphia Franklin Institute, 11 miles northwest). NOAA, through RCC-ACIS.
