Deerfield’s center stands about 1,130 ft above sea level. Within three miles the land runs from 990 ft to 1,250 ft, a difference of 260 ft: rolling country.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. 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 24 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 Deerfield reaches Lake Michigan by way of the West Branch White, the White River and the Fox River: about 130 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124 and Lake Butte des Morts.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Deerfield; river miles along the main stem, rounded.
