The Harmony plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Harmony’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,460 ft to 1,640 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Mafic metavolcanic rocks (basalt, basaltic-andesite), from the Paleoproterozoic, 1.6 to 2.5 billion years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. 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 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 Harmony reaches the Gulf of America by way of Thunder Creek, the North Fork Jump, the Jump, the Chippewa and the Mississippi: about 1,910 river miles.
Lakes on the way: Lake Wissota and Holcombe Flowage.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Harmony; river miles along the main stem, rounded.
