The surprise sighting of this hike was a beaver swimming in the cove at the beginning of the dam. He slapped his tail at me and swam away, but I found him again out a little ways. I saw he was heading back to the cove again, so I took a path to the water's edge, crouched down and waited for him to swim by. He was really quite close. After he passed, I stood and walked a bit closer and got a 2nd tail slap for my efforts!
