The Norwegian Grove 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.
Norwegian Grove’s center stands about 1,330 ft above sea level. Within three miles the land runs from 1,190 ft to 1,400 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Mafic metavolcanic rocks (metabasalt, greenstone), from the Neoarchean, 2.5 to 2.8 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 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 11 mi of the line.
Graywacke, mudstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 7 mi of the line.
Granite, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.

A raindrop that lands in Norwegian Grove reaches Hudson Bay by way of Deerhorn Creek, the South Branch Buffalo, the Buffalo, the Red River of the North and the Nelson: about 1,170 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
420 miles of the trip are on the Red River of the North.
