The Morristown plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
74° on Nov. 14, 1999, the hottest reading for this week of the year since 1914. Next is 74° in 2012.
Morristown’s center stands about 1,010 ft above sea level. Within three miles the land runs from 980 ft to 1,130 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Klondike Hill, about 1,180 ft, 13 miles west.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 3 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.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 12 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 11 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 0.8 mi of the line.

A raindrop that lands in Morristown reaches the Gulf of America by way of the Cannon and the Mississippi: about 1,850 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Morristown; river miles along the main stem, rounded.
Morristown has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 5° in January. A normal year brings about 52 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Morristown normally reaches 42° and falls to 25°. The record high is 74°, in 1999; the record low −9°, in 1959. The most rain on this date, 0.79 in, fell in 1951.
