There are 3 or 4 larger falls where the river flows off of sharp edges of the shale. Most of the river is quite shallow as it spreads across the flat rocks. The water itself is tinted brown and has a lot of foam, not because it is dirty, but because of organic matter in the soils that the water flows through. The trails wind through the shady forest and there are frequent overlooks and places to go and wade around in the stream. This time of year it is warm and pleasant but I'm sure in the spring that river is a real rip snorter. They get a lot of snow here! We found crawdads in the pools and some interesting invertebrate larvae that were attached, head down, to the rocks in the shallow riffles. There were very circular holes drilled into the shale where rocks just ground the rock down during high water flow.
As the river flowed into Superior it formed a nice big pool just daring Thayer to skinny dip in. It looked inviting but I declined to join him and was glad I didn't because, shortly after he got in, a herd of young boys and their dippy mom/aunt came down to skip rocks for half an hour. Wouldn't want to traumatize any youngsters!
The shales in this area were really interesting because they were petrified sand ripples and were broken in such a way that you could see that each layer had a different color, direction of ripples and texture. I hope my pictures will illustrate that for you. See if you can match the picture to something I described...
