70° on Nov. 15, 2025, the hottest reading for this week of the year since 1940. Next is 65° in 2010.
Elk River’s center stands about 890 ft above sea level. Within three miles the land runs from 840 ft to 1,080 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Middle and Upper Cambrian (sandstone, siltstone, shale), from the Middle Cambrian to Cambrian, 487 to 521 million years old.
The section below crosses 2 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.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 14 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 10 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 Elk River reaches the Gulf of America by way of Trott Brook, the Rum and the Mississippi: about 1,870 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Elk River; river miles along the main stem, rounded.
Elk River has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 3° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 33 inches of water.
