King Boreas:
I was close today, but didn't have the vehicle, the time, or the ambition. Water is up everywhere, and any shortcuts I might have considered would not be fun.
I have no idea when I'll be back.
If I go during the summer, or in October or November, I'll try to restore it. There are many memorable stories about the beaver dam. Maybe I'll collect them and post them.
