77° on Nov. 16, 1993, the hottest reading for this week of the year since 1893. Next is 76° in 2020.
Leverett’s center stands about 460 ft above sea level. Within three miles the land runs from 170 ft to 1,240 ft, a difference of 1,070 ft: steep hill country. The highest named summit within 15 miles is Moore Hill, about 1,710 ft, 14 miles west.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arkose, siltstone, sandstone. Age: Late Triassic, 202 to 237 million years old. About 8 mi of the line.
Biotite-gneiss, amphibolite. Age: Late Ordovician to Silurian, 440 to 454 million years old. About 5 mi of the line.
Gneiss. Age: Neoproterozoic, 610 to 616 million years old. About 3 mi of the line.
Gneiss, quartzite, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Mica-schist. Age: Late Ordovician, 449 to 453 million years old. About 3 mi of the line.
Schist, phyllite. Age: Early Devonian, 394 to 422 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. 2 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 Leverett reaches Long Island Sound and the Atlantic Ocean by way of Mountain Brook, Doolittle Brook, the Mill and the Connecticut: about 110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Leverett; river miles along the main stem, rounded.
Leverett has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 14° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Leverett normally reaches 50° and falls to 30°. The record high is 71°, in 1973; the record low 10°, in 1986. The most rain on this date, 1.12 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Amherst, 5 miles south-southwest, 320 ft lower. NOAA, through RCC-ACIS.
