Nore’s center stands about 1,420 ft above sea level. Within three miles the land runs from 1,370 ft to 1,480 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Foliated to gneissic tonalite, granodiorite, and diorite (tonalite, granodiorite, diorite), from the Neoarchean, 2.5 to 2.8 billion years old.
The section below crosses 3 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.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 16 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 7 mi of the line.
Felsic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Nore straddles the Laurentian Divide. Rain on the south side runs to the Gulf of America; most of the rest goes to Hudson Bay.
From the center of town, a raindrop reaches Hudson Bay by way of the Blackduck, the Red Lake, the Red River of the North and the Nelson: about 1,200 river miles. Past the border it runs north through Canada to Hudson Bay. One that lands on the south side reaches the Gulf of America by way of Sugar Lake and the Mississippi: about 2,240 river miles.
Lakes on the way: Upper Red 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 Nore; river miles along the main stem, rounded.
