The section below crosses 7 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.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 5 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 5 mi of the line.
Dolostone, limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 5 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 388 million years old. About 4 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian, 315 to 324 million years old. About 2 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 374 million 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. 1 smaller unit along the line are not listed.

A raindrop that lands in New Boston reaches the Gulf of America by way of Eliza Creek and the Mississippi: about 1,410 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Boston; river miles along the main stem, rounded.
