69° on Nov. 17, 1953, the hottest reading for this week of the year since 1887. Next is 68° in 1999.
Long Lake’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,180 ft to 1,320 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Warren Hill, about 1,470 ft, 13 miles east.
Under the town center the state geologic map shows Interlayered volcanic and sedimentary rocks (volcanic, sedimentary), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
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 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.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 15 mi of the line.
Schist, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Volcanic, sedimentary. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion 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.

A raindrop that lands in Long Lake reaches the Gulf of America by way of Hay Creek, the Nokasippi and the Mississippi: about 1,980 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Long Lake; river miles along the main stem, rounded.
Long Lake has a dry-winter warm-summer continental climate. Summer afternoons average 82° in July; winter nights fall to about 0° in January. About 24 inches of rain fall in a normal year.
On November 14 Long Lake normally reaches 40° and falls to 22°. The record high is 67°, in 1953; the record low −5°, in 1986. The most rain on this date, 0.55 in, fell in 1997.
