So I’ve been hiking all over Manitoulin Island in Ontario for pretty much my entire life. (It’s in northern Lake Huron).

Even if you’re well off any trails, you never need a compass. The glaciers pushed down from the north, and left deep gouges in the exposed rock as they pushed south.

Just look for the gouges in the exposed fossilized coral reefs. They’re all north/south. The entire island is a compass.
