81° on Nov. 15, 1993, the hottest reading for this week of the year since 1864. Next is 78° in 1990.
Mount Laurel’s center stands about 90 ft above sea level. Within three miles the land runs from 20 ft to 120 ft, a difference of 100 ft: gently rolling country.
The section below crosses 9 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 5 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 4 mi of the line.
Sand. Age: Late Cretaceous, 72 to 84 million years old. About 3 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 3 mi of the line.
Clay, sand. Age: Early Miocene, 16 to 23 million years old. About 3 mi of the line.
Clay, silt. Age: Late Cretaceous, 72 to 84 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. 3 smaller units along the line are not listed.

A raindrop that lands in Mount Laurel reaches Delaware Bay and the Atlantic Ocean by way of Parkers Creek, Rancocas Creek and the Delaware: about 90 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mount Laurel; river miles along the main stem, rounded.
Mount Laurel has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 26° in January. About 49 inches of rain fall in a normal year.
On November 14 Mount Laurel normally reaches 57° and falls to 38°. The record high is 75°, in 1993; the record low 18°, in 1986. The most rain on this date, 0.93 in, fell in 1972.
Normals 1991–2020 and records since 1864 at Moorestown 4 E, 3 miles north-northeast. NOAA, through RCC-ACIS.
