This is an historic walking bridge in Jay Cooke State Park in Minnesota. Last spring the area received way too much rain in too short of a time. As a result there was some devastating damage from the flooding that resulted.
You can see the current water level. On average it doesn't get too much higher. But during and after the rainfall he water in this river was a couple feet above the level of the walking surface of the bridge. It is a fast moving stream on a good day. To cause this damage you can imagine what the water was like.
I can recall walking on this bridge as a child 45 years ago. To see it looking like this was like seeing an old friend lying in a hospital bed after a major accident.
