On our way home, back to the bridge, we found this steel ring forever locked in this boulder. Normally, the water level is high enough that we didn't even know this existed, but with the horrible, dangerously low levels we're experiencing right now . . . this discovery was the silver lining to our continued drought.
The loggers at the CCC camp right here at the corner of our property used to dam up the river with logs and then, when the water level was high enough and the logs all accumulated, they would release the dam allowing the logs to rush up (we're north of the Laurentian Divide) the river into the Pigeon and then down to Lake Superior where they would be floated to various mills and/or railroad yards around the big lake.
