82° on Nov. 14, 1999, the hottest reading for this week of the year since 1900. Next is 80° in 1911.
Morrisville’s center stands about 1,090 ft above sea level. Within three miles the land runs from 900 ft to 1,150 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Lucas Knob, about 1,340 ft, 14 miles east-southeast.
Under the town center the state geologic map shows Osagean Series (limestone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 13 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.8 mi of the line.

A raindrop that lands in Morrisville reaches the Gulf of America by way of the Little Sac, the Sac, the Osage, the Missouri and the Mississippi: about 1,600 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Morrisville; river miles along the main stem, rounded.
Morrisville has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. About 46 inches of rain fall in a normal year.
