Poole’s center stands about 480 ft above sea level. Within three miles the land runs from 400 ft to 530 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Steamport Hill, about 640 ft, 8 miles east-southeast.
Under the town center the state geologic map shows Sturgis Formation (siltstone), from the Carboniferous, 299 to 324 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 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.
Siltstone. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 8 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 Poole reaches the Gulf of America by way of Whitelick Creek, Highland Creek, the Ohio and the Mississippi: about 1,140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Poole; river miles along the main stem, rounded.
