Stony River’s center stands about 1,750 ft above sea level. Within three miles the land runs from 1,650 ft to 1,850 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Stony Tower Hill, about 2,100 ft, 6 miles southeast.
Under the town center the state geologic map shows Gabbro, from the Mesoproterozoic, 1 to 1.2 billion years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Mesoproterozoic, 1 to 1.2 billion years old. About 10 mi of the line.
Anorthosite. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 7 mi of the line.
Volcanic. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Age: Mesoproterozoic, 1 to 1.2 billion years old. About 3 mi of the line.
Volcanic. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.9 mi of the line.
Felsic-hypabyssal, monzodiorite, gabbro. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 0.5 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 Stony River reaches Hudson Bay by way of Camp East Creek, the Stony, the South Kawishiwi, the Bottle, the Loon, the Rainy, the Winnipeg and the Nelson: about 1,130 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Lake of the Woods, Rainy Lake, Basswood Lake and Lake Winnipeg.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stony River; river miles along the main stem, rounded.
