71° on Nov. 11, 2020, the hottest reading for this week of the year since 1918. Next is 67° in 2002.
Pittsburg’s center stands about 1,340 ft above sea level. Within three miles the land runs from 1,170 ft to 2,270 ft, a difference of 1,100 ft: steep hill country. The highest named summit within 15 miles is Stub Hill, about 3,630 ft, 15 miles east-northeast.
Under the town center the state geologic map shows Frontenac Formation, undivided (metagraywacke, slate), from the Silurian, 422 to 445 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagraywacke, slate. Age: Silurian, 422 to 445 million years old. About 9 mi of the line.
Phyllite, metasandstone. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Metaclastic. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Metavolcanic. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.
Metabasalt. Age: Silurian, 422 to 445 million years old. About 0.7 mi of the line.
Metabasalt. Age: Silurian, 425 to 434 million years old. About 0.5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Pittsburg reaches Long Island Sound and the Atlantic Ocean by way of Coon Brook and the Connecticut: about 390 river miles.
Lake on the way: Connecticut Lakes.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pittsburg; river miles along the main stem, rounded.
Pittsburg has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 0° in January. A normal year brings about 143 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Pittsburg normally reaches 40° and falls to 24°. The record high is 59°, in 2010; the record low −1°, in 2019. The most rain on this date, 0.72 in, fell in 1948.
Normals 1991–2020 and records since 1918 at First Connecticut Lake, 6 miles east-northeast, 310 ft higher. NOAA, through RCC-ACIS.
