This morning as we walked through the dense brush on the bank between the Rinehart Canyon cliffs and the Grande Ronde River, I heard a yelp up ahead, not sure whether it came from Kim or Charlie, who were perhaps 30 yards in front of me, invisible. I could only see a few feet ahead as the foliage was about head-high and the path was tightening, so I saw nothing out of the ordinary. But in a couple of seconds my phone rang and Kim was reporting that Charlie, walking ahead of her, stepped right over what she presumed to be a dead rattlesnake, but as she got near, it suddenly coiled and emitted an audible warning. She said that she dove through the brush at the side of the path to get past, and advised me to do the same. Some visuals:
