Searsport’s center stands about 50 ft above sea level. Within three miles the land runs from 10 ft to 390 ft, a difference of 380 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Spears Mountain, about 1,150 ft, 15 miles west.
Under the town center the state geologic map shows Penobscot Formation (slate, schist, quartzite), from the Middle Ordovician to Late Ordovician, 450 to 470 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 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 3 mi of the line.
Metasedimentary, metavolcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 2 mi of the line.
Slate, schist, quartzite. Age: Middle Ordovician to Late Ordovician, 450 to 470 million years old. About 2 mi of the line.
Sandstone, limestone. Age: Ordovician to Devonian, 359 to 487 million years old. About 1 mi of the line.
Schist. Age: Silurian, 422 to 445 million years old. About 0.9 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 Searsport reaches the Atlantic Ocean by way of Mill Brook: about 1 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Searsport; river miles along the main stem, rounded.
Searsport has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 9° in January. A normal year brings about 75 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Searsport normally reaches 46° and falls to 30°. The record high is 63°, in 2005; the record low 8°, in 2019. The most rain on this date, 1.56 in, fell in 2006.
Normals 1991–2020 and records since 1925 from the Bangor Area threaded record (Bangor International Airport, 24 miles north-northeast). NOAA, through RCC-ACIS.
