Silver Cliff’s center stands about 1,280 ft above sea level. Within three miles the land runs from 1,120 ft to 1,370 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is McCaslin Mountain, about 1,640 ft, 6 miles southwest.
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 29×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite, granodiorite. Age: Paleoproterozoic, 1.8 to 1.9 billion years old. About 12 mi of the line.
Metavolcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion 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 Silver Cliff reaches Lake Michigan by way of Homestead Creek, Eagle Creek and the Peshtigo: about 85 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
70 miles of the trip are on the Peshtigo.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Silver Cliff; river miles along the main stem, rounded.
