78° on Nov. 16, 1993, the hottest reading for this week of the year since 1931. Next is 76° in 1973.
Morris’s center stands about 460 ft above sea level. Within three miles the land runs from 280 ft to 780 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Bowling Green Mountain, about 1,420 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Quartz-Oligoclase Gneiss, from the Mesoproterozoic, 1 to 1.6 billion years old.
The section below crosses 15 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.
Sandstone, siltstone, mudstone. Age: Early Jurassic, 175 to 202 million years old. About 6 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Dolostone. Age: Early Cambrian to Middle Cambrian, 497 to 542 million years old. About 3 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 million years old. About 2 mi of the line.
Granite. Age: Mesoproterozoic, 1.1 to 1.1 billion years old. About 1 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion 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. 9 smaller units along the line are not listed.

A raindrop that lands in Morris reaches New York Harbor and the Atlantic Ocean by way of the Whippany and the Passaic: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Morris; river miles along the main stem, rounded.
Morris 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 Morris 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, 8 miles east-southeast, 280 ft lower. NOAA, through RCC-ACIS.
