Never did figure out exactly where I camped. Was supposed to be Cabin Bottom but I couldn't find any way through the tamarisks nor much in the way of a sandbar. So camped on the east shore thinking it was Tuxedo Bottom somewhere. A chat the next day confirmed it wasn't Tuxedo. Site must have been just opposite where Valentine and Cabin Bottoms merged. And yet if that was true, this didn't look much like the Rincon that should be located there.
