Lowell’s center stands about 980 ft above sea level. Within three miles the land runs from 790 ft to 2,070 ft, a difference of 1,280 ft: steep hill country. The highest named summit within 15 miles is Jay Peak, about 3,810 ft, 9 miles north-northwest.
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 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Muscovite-schist, gneiss, quartzite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 8 mi of the line.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 3 mi of the line.
Phyllite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Metasandstone, metacarbonate, phyllite. Age: Silurian to Early Devonian, 394 to 425 million years old. About 2 mi of the line.
Phyllite, muscovite-schist, quartzite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Phyllite. Age: Cambrian, 487 to 542 million years old. About 1 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 Lowell reaches the St. Lawrence River by way of the East Branch Missisquoi, the Missisquoi and the Richelieu: about 210 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
90 miles of the trip are on the Missisquoi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lowell; river miles along the main stem, rounded.
