Lava rapid is created where the river cuts through a basalt lava dike. There is a 2' to 3' entrance drop into a small eddy. From here you can scout the drop. Running down the middle or left will lead you directly into a fairly large hole. The right side of the drop is gaurded by a piece of ledge that creates a large roostertail. The best route is starting from the middle of the channel and run towards the right just skirting the roster tail ledge.
