Magnetic Rock

Follow the well-worn trail through the woods, past a pond, ending at the 60-foot high Magnetic Rock. This bedrock outcrop has lots of magnetite, the most magnetic of all the naturally-occurring minerals on Earth. Pull out your compass and watch it react. The trail includes areas affected by the 1999 blowdown, 2002 prescribed burn, and 2007 Ham Lake wildfire, all good areas to keep an eye out for blueberries.

From Highway 61 in Grand Marais, drive north on the Gunflint Trail about 47 miles to a small parking area on the east side of the road
