70° on Nov. 17, 1953, the hottest reading for this week of the year since 1887. Next is 70° in 2023.
Eagle River’s center stands about 640 ft above sea level. Within three miles the land runs from 590 ft to 1,260 ft, a difference of 670 ft: hilly country. The highest named summit within 15 miles is Mount Horace Greeley, about 1,530 ft, 7 miles east-southeast.
Under the town center the state geologic map shows Copper Harbor Conglomerate (conglomerate, sandstone), from the Mesoproterozoic, 1 to 1.6 billion years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 22×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt. Age: Mesoproterozoic, 1.1 to 1.1 billion years old. About 9 mi of the line.
Sandstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Conglomerate, sandstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.5 mi of the line.

A raindrop that lands in Eagle River reaches Lake Superior by way of Garden City Creek: about 1 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eagle River; river miles along the main stem, rounded.
Eagle River has a cold desert climate. Summer afternoons average 75° in July; winter nights fall to about 9° in February. Barely 0.0 inches of rain fall in a normal year.
On November 14 Eagle River normally reaches 38° and falls to 27°. The record high is 59°, in 1909; the record low 6°, in 1933. The most rain on this date, 0.95 in, fell in 1944.
Normals 1991–2020 and records since 1887 at Hancock Houghton County Airport, 19 miles south-southwest, 420 ft higher. NOAA, through RCC-ACIS.
