Trail Conditions
No reports yet
Nemadji State Forest is Minnesota's muddy challenge, where ancient glacial clay deposits create trail conditions that test even experienced off-roaders. After rain, the clay roads become skating rinks of red-brown mud that can swallow vehicles and defeat even aggressive mud tires. During dry spells, the same roads offer moderate, enjoyable forest driving through dense pine and hardwood forest near Lake Superior.
Fun Facts
Nemadji State Forest sits on ancient lake clay deposits left by glacial Lake Duluth.
The clay soil turns into some of the slipperiest mud in the Midwest when wet.
The Nemadji River is one of the most polluted in Minnesota due to natural clay erosion.
