Malung’s center stands about 1,060 ft above sea level. Within three miles the land runs from 1,050 ft to 1,120 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Schist of sedimentary protolith, 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 64×. 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 9 mi of the line.
Schist. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.
Orthogneiss. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 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 Malung reaches Hudson Bay by way of the Roseau, the Red River of the North and the Nelson: about 860 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: 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 Malung; river miles along the main stem, rounded.
