The Shevlin 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.
Shevlin’s center stands about 1,450 ft above sea level. Within three miles the land runs from 1,430 ft to 1,540 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Granitic intrusion, from the Neoarchean, 2.5 to 2.8 billion years old.
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 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 21 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.

Shevlin straddles the Laurentian Divide. Rain on the northwest side runs to Hudson Bay; most of the rest goes to the Gulf of America.
From the center of town, a raindrop reaches the Gulf of America by way of the Mississippi: about 2,300 river miles. One that lands on the northwest side reaches Hudson Bay by way of the Clearwater, the Red Lake, the Red River of the North and the Nelson: about 1,160 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Sugar Lake, Buck Lake, Lake Pepin and Lake Bemidji.
1,750 miles of the trip are on the Mississippi.
