gone on the river
The first few days on the river, I struggled with a number of beaver dams. They're tough to deal with, and I ended up with soaked shoes for my efforts to get past one of them.
Since Bemidji, the dams I've encountered have been human-made. They're also a pain in my ass. Not only because I have to portage around them, but because they stack up unmoving lakes of water that wants to move, but can't get through.
I fear this will be a pattern until just above St. Louis.
