Eau Galle’s center stands about 780 ft above sea level. Within three miles the land runs from 730 ft to 1,090 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Tuttle Hill, about 1,220 ft, 8 miles west-northwest.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 34×. 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. Age: Cambrian, 487 to 542 million years old. About 21 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 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 Eau Galle reaches the Gulf of America by way of Missouri Creek, the Eau Galle, the Chippewa and the Mississippi: about 1,770 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eau Galle; river miles along the main stem, rounded.
Eau Galle has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 4° in January. About 35 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1903 at Durand, 5 miles south-southeast. NOAA, through RCC-ACIS.
