Cleon’s center stands about 850 ft above sea level. Within three miles the land runs from 790 ft to 1,150 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Briar Hill, about 1,740 ft, 13 miles southeast.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Shale. Age: Carboniferous, 324 to 359 million years old. About 9 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 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.
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 Cleon reaches Lake Michigan by way of First Creek, Bear Creek and the Manistee: about 50 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cleon; river miles along the main stem, rounded.
