Peck’s center stands about 790 ft above sea level. Within three miles the land runs from 750 ft to 830 ft, a difference of 80 ft: gently rolling country.
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.
Shale. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 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 Peck reaches Lake St. Clair by way of the Potts Drain, Elk Creek, the Black River and the Saint Clair: about 110 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 Black River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Peck; river miles along the main stem, rounded.
