Magnetic Rock Trail

Magnetic Rock Trail Professional Review and Guide

"The trail goes through a burn area over exposed bedrock, then to deep woods and a strange looking monolithic rock with magnetic properties. Under normal circumstances, a glacial erratic (a boulder dropped from a glacial ice sheet) wouldn’t get much attention in Minnesota. They are, after all, just big rocks that you can find almost everywhere, including in people’s front yards.

But this one is special, not just for its magnetic properties, but also for its appearance. The rock’s dimensions are 10 by 20 by 30 feet and it is shaped like a big monument that seems to have dropped out of the sky. Multi-colored lichens cover the rock’s surface giving it various shades of yellow and orange. Its magnetism comes from the mineral magnetite, common to the underlying bedrock of the Gunflint Iron Formation. Special attractions: The rock (bring a compass to test out its magnetic properties) and wildlife."

Wow! There's nothing like the north woods of Minnesota and it doesn't get too much more remote than this. Magnetic Rock is actually a 20 - 30 foot tall rock that may actually be magnetic. I didn't have anything metal along with me so it was hard to know for sure.
