Freedom’s center stands about 1,620 ft above sea level. Within three miles the land runs from 1,540 ft to 1,760 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Sugarbush Hill, about 1,980 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Mafic to felsic metavolcanic rocks, 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 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 15 mi of the line.
Rhyolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Quartzite, conglomerate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Basalt, andesite. Age: Paleoproterozoic, 1.9 to 1.9 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.
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 Freedom reaches Lake Michigan by way of Richardson Creek, the North Branch Oconto and the Oconto: about 120 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
60 miles of the trip are on the North Branch Oconto.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Freedom; river miles along the main stem, rounded.
