78° on Nov. 16, 1993, the hottest reading for this week of the year since 1931. Next is 76° in 1973.
Harding’s center stands about 400 ft above sea level. Within three miles the land runs from 230 ft to 720 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Mount Arlington, about 1,250 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Towaco Formation (sandstone, siltstone-mudstone), from the Early Jurassic, 175 to 202 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Sandstone-mudstone, siltstone-mudstone. Age: Early Jurassic to Late Jurassic, 145 to 202 million years old. About 4 mi of the line.
Sandstone, siltstone-mudstone. Age: Early Jurassic, 175 to 202 million years old. About 3 mi of the line.
Sandstone, siltstone, mudstone. Age: Early Jurassic, 175 to 202 million years old. About 3 mi of the line.
Granite. Age: Mesoproterozoic, 1.1 to 1.1 billion years old. About 2 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 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. 8 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 Harding reaches New York Harbor and the Atlantic Ocean by way of the Passaic: about 80 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Harding; river miles along the main stem, rounded.
Harding 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 24 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Harding normally reaches 55° and falls to 35°. The record high is 71°, in 1964; the record low 11°, in 1986. The most rain on this date, 1.51 in, fell in 1937.
Normals 1991–2020 and records since 1931 at Canoe Brook, 7 miles east, 220 ft lower. NOAA, through RCC-ACIS.
