70° on Nov. 11, 2020, the hottest reading for this week of the year since 1976. Next is 68° in 2022.
Searsmont’s center stands about 220 ft above sea level. Within three miles the land runs from 180 ft to 500 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is Mount Megunticook, about 1,370 ft, 10 miles southeast.
Under the town center the state geologic map shows Devonian - Ordovician Bucksport Formation (sandstone, limestone), from the Ordovician to Devonian, 359 to 487 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 22×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Slate, schist, quartzite. Age: Middle Ordovician to Late Ordovician, 450 to 470 million years old. About 9 mi of the line.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 3 mi of the line.
Schist. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 2 mi of the line.
Sandstone, limestone. Age: Ordovician to Devonian, 359 to 487 million years old. About 2 mi of the line.
Granite. Age: Devonian, 359 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. 7 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 Searsmont reaches the Atlantic Ocean by way of the Saint George: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Searsmont; river miles along the main stem, rounded.
Searsmont has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 12° in January. A normal year brings about 69 inches of snow; with the rain, that comes to about 56 inches of water.
On November 14 Searsmont normally reaches 47° and falls to 32°. The record high is 65°, in 2010; the record low 8°, in 1986. The most rain on this date, 1.47 in, fell in 2018.
Normals 1991–2020 and records since 1976 at West Rockport 1 NNW, 12 miles south-southeast, 140 ft higher. NOAA, through RCC-ACIS.
