The Forest 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.
Forest’s center stands about 1,300 ft above sea level. Within three miles the land runs from 910 ft to 1,370 ft, a difference of 460 ft: hilly country.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 million years old.
The section below crosses 2 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.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 13 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 12 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 Forest reaches the Gulf of America by way of Billings Creek, the Kickapoo, the Wisconsin and the Mississippi: about 1,730 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Forest; river miles along the main stem, rounded.
