Lee’s center stands about 1,290 ft above sea level. Within three miles the land runs from 1,240 ft to 1,350 ft, a difference of 110 ft: gently rolling country.
The section below crosses 9 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.
Orthogneiss. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.
Volcanic, sedimentary. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Volcanic, sedimentary, hypabyssal. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 3 mi of the line.
Banded-iron-formation. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
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 Lee reaches the Gulf of America by way of the Rice and the Mississippi: about 2,090 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lee; river miles along the main stem, rounded.
