75° on Nov. 11, 2020, the hottest reading for this week of the year since 1936. Next is 72° in 2012.
Hailesboro’s center stands about 480 ft above sea level. Within three miles the land runs from 410 ft to 670 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Big Hill, about 1,290 ft, 15 miles southeast.
Under the town center the state geologic map shows Calcitic and dolomitic marble, from the Mesoproterozoic, 1 to 1.6 billion years old.
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 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Marble. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 12 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Marble. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.8 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.

A raindrop that lands in Hailesboro reaches the St. Lawrence River by way of the Oswegatchie and the Saint Lawrence: about 120 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Saint Lawrence.
70 miles of the trip are on the Oswegatchie.

Hailesboro has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 5° in January. A normal year brings about 92 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Hailesboro normally reaches 46° and falls to 27°. The record high is 66°, in 1989; the record low −4°, in 2019. The most rain on this date, 0.70 in, fell in 1951.
Normals 1991–2020 and records since 1936 at Gouverneur 3 NW, 4 miles northwest. NOAA, through RCC-ACIS.
