Cape Vincent’s center stands about 270 ft above sea level. Within three miles the land runs from 240 ft to 340 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Trenton Group (limestone), from the Middle Ordovician, 459 to 471 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 11 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Cape Vincent reaches Lake Ontario by way of Kents Creek: about 6 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cape Vincent; river miles along the main stem, rounded.
Cape Vincent has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 10° in January. About 37 inches of rain fall in a normal year.
On November 14 Cape Vincent normally reaches 47° and falls to 30°. The record high is 68°, in 1994; the record low 13°, in 1996. The most rain on this date, 0.90 in, fell in 1985.
Normals 1991–2020 and records since 1949 at Watertown International Airport, 18 miles east-southeast. NOAA, through RCC-ACIS.
