The Wolf River plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Wolf River’s center stands about 1,480 ft above sea level. Within three miles the land runs from 1,270 ft to 1,570 ft, a difference of 300 ft: rolling country.
Under the town center the state geologic map shows Wolf River batholith; Hager Formation; Rhyolite member, from the Mesoproterozoic, 1 to 1.6 billion years old.
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 23×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Rhyolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 11 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 8 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Basalt, basaltic-andesite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.

A raindrop that lands in Wolf River reaches Lake Michigan by way of Rose Lake Creek, Dalton Creek, the South Branch Oconto and the Oconto: about 100 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 Oconto.
