Berlin’s center stands about 800 ft above sea level. Within three miles the land runs from 790 ft to 860 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Twombly Mountain, about 1,150 ft, 11 miles southwest.
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.
Shale. Age: Carboniferous, 324 to 359 million 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 Berlin reaches Lake St. Clair by way of the Belle and the Saint Clair: about 75 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
55 miles of the trip are on the Belle.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Berlin; river miles along the main stem, rounded.
