The Lutsen 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.
Lutsen’s center stands about 1,780 ft above sea level. Within three miles the land runs from 1,540 ft to 1,970 ft, a difference of 430 ft: hilly country. The highest named summit within 15 miles is Eagle Mountain, about 2,300 ft, 10 miles northeast.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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, andesite. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 8 mi of the line.
Basalt, basaltic-andesite. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 3 mi of the line.
Mafic-hypabyssal, diorite. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 2 mi of the line.
Basalt. Age: Mesoproterozoic, 1 to 1.2 billion years old. About 2 mi of the line.
Basalt. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gabbroic. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.
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 Lutsen reaches Lake Superior by way of Mistletoe Creek and the Poplar: about 17 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
