Prospect’s center stands about 840 ft above sea level. Within three miles the land runs from 180 ft to 890 ft, a difference of 710 ft: hilly country. The highest named summit within 15 miles is Lindsley Hill, about 1,070 ft, 9 miles north.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granofels. Age: Middle Ordovician, 459 to 471 million years old. About 4 mi of the line.
Schist. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 3 mi of the line.
Schist, granofels. Age: Silurian to Devonian, 359 to 445 million years old. About 3 mi of the line.
Schist, phyllite. Age: Silurian to Devonian, 359 to 445 million years old. About 3 mi of the line.
Schist. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Arkose. Age: Late Triassic to Early Jurassic, 175 to 237 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. 6 smaller units along the line are not listed.

A raindrop that lands in Prospect reaches Long Island Sound and the Atlantic Ocean by way of Mixville Brook, the Tenmile and the Quinnipiac: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Prospect; river miles along the main stem, rounded.
Prospect has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 23° in January. About 42 inches of rain fall in a normal year.
On November 14 Prospect normally reaches 54° and falls to 36°. The record high is 69°, in 1959; the record low 20°, in 2019. The most rain on this date, 2.19 in, fell in 1972.
Normals 1991–2020 and records since 1948 at New Haven Tweed Airport, 17 miles south-southeast, 830 ft lower. NOAA, through RCC-ACIS.
