68° on Nov. 12, 2020, the hottest reading for this week of the year since 1931. Next is 66° in 2012.
Eagle Bay’s center stands about 1,780 ft above sea level. Within three miles the land runs from 1,700 ft to 2,330 ft, a difference of 630 ft: hilly country. The highest named summit within 15 miles is Little Moose Mountain, about 3,610 ft, 14 miles east-southeast.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metasedimentary, gneiss. 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.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.

A raindrop that lands in Eagle Bay reaches Lake Ontario by way of First Lake, the Middle Branch Moose, the Moose and the Black River: about 120 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: First Lake.
75 miles of the trip are on the Black River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eagle Bay; river miles along the main stem, rounded.
Eagle Bay has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 7° in January. A normal year brings about 154 inches of snow; with the rain, that comes to about 50 inches of water.
Normals 1991–2020 and records since 1931 at Big Moose 3 SE, 4 miles northwest, 160 ft higher. NOAA, through RCC-ACIS.
