Lynne’s center stands about 1,630 ft above sea level. Within three miles the land runs from 1,560 ft to 1,700 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Pearson Hill, about 1,980 ft, 15 miles southwest.
Under the town center the state geologic map shows Granite-tonalite (granite, tonalite, gneiss), from the Paleoproterozoic, 1.8 to 1.9 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 59×. 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, basaltic-andesite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 9 mi of the line.
Granite, tonalite, gneiss. Age: Paleoproterozoic, 1.8 to 1.9 billion years old. About 8 mi of the line.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 8 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 Lynne reaches the Gulf of America by way of Brant Creek, the Somo, the Wisconsin and the Mississippi: about 1,950 river miles.
Lakes on the way: Petenwell Lake, Lake Wisconsin, Lake Du Bay and Wisconsin River Flowage 4964.
1,610 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lynne; river miles along the main stem, rounded.
