Middletown’s center stands about 1,380 ft above sea level. Within three miles the land runs from 1,370 ft to 1,500 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated (conglomerate, sandstone, mudstone), from the Late Cretaceous, 72 to 100 million years old.
The section below crosses 2 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.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 15 mi of the line.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 9 mi of the line.

A raindrop that lands in Middletown reaches the Gulf of America by way of Stony Brook, the Des Moines and the Mississippi: about 1,760 river miles.
Lakes on the way: Roberts Creek and Big Creek Pounding Area.
1,330 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Middletown; river miles along the main stem, rounded.
Middletown has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 7° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 29 inches of water.
On November 14 Middletown normally reaches 43° and falls to 26°. The record high is 72°, in 1953; the record low 4°, in 2014. The most rain on this date, 1.04 in, fell in 1902.
