On my North Shore hike today, I found this cool tunnel, formed by huge slabs of rock coming off of a cliff and stacking up like playing cards. I'm sorry to say this, but it reminded me most of the tunnel on the 18th hole of the minigolf course in Grand Marais.
But where was it? It was right off of the Superior Hiking Trail, for one thing.
Here's another hint:
I don't know who named this particular feature of the SHT, but I think it should be "Picnic Rocks" plural, since the main feature at the end of the spur trail wasn't a big overlook atop some rock perfect for lunch, but this amazing pile of rocks,some of which might actually work as a picnic table.
One more photo hint. This is 0.4 miles further up the SHT:
