Yeah, yeah, I know that this looks like I put these rocks there going for some sort of dubious and unrealistic "aesthetic effect" but I really didn't put the rocks where they are...and I didn't see any other tracks there either. This was right on the shore of Lake Superior and it would be possible that particularly violent winter storm waves washed these up here. And what initially caught my eye was the circular patterns in the striations in the rock. Pretty wild to think about the forces that caused that.

This tree was growing right on the shore of Lake Superior. As you can see the bank eroded over the years of the trees' life and left it hanging out over thin air. But you can also see that the tree isn't dead.

This rock was right on the shore of Lake Superior. Obviously the white rock (quartz of some kind?) is harder - and more resistant to erosion - than the grey. But that just about exhausts my knowledge of geology.

I went for a walk along a breaker (I'm not sure if that's the word to use - it's a thing that sticks out into a body of water - Lake Superior in this case - and protects a harbor from the big waves of the open lake) and saw this rock. Waves crashing on the breaker during winter storms had sprayed up on this rock and frozen to make this thin layer of ice. It then warmed up and the layer of ice started to melt which is why the ice looks grey (actually the ice isn't really grey, it is just melting and has cracked in so many places that there's almost as much white - from the cracks - as there is clear ice.) The green blobs you see are lichens growing on the rock.

This is a chunk of ice that washed up on Lake Superior's shore.

This chunk of ice looks kind of like those shiny rocks that have been put in a rock tumbler to take any roughness off of them.
