I follow a guy on YouTube whose channel is called the Life of Luke. He goes hiking, paddling and parasailing with his dog who is named Luke. Recently he posted an awesome video packrafting the Cline River in the Rockies.
They're on inflatable kayaks and have to pack them on their backs for quite a while so it's a bit beyond me. I had a neighbor who did that on Widgeon Lake. It's a long haul with a heavy pack. In this video they made a wise choice to hike around a narrow channel of very fast moving water. In a whitewater kayak it might have been OK but they were in inflatable kayaks and the guy had his dog with them so they decided to hike around.
Earlier on in the video it was shallow and rocky. They ended up getting a tear in once of the inflatable kayaks and had to repair it before continuing. The striking point of the video begins at 20:25. At that point the river really becomes pristine.
It reminds me of another video he did in an inflatable kayak on the Capilano river in Vancouver just below the fish hatchery. At 4:04 of that video the river opens up to a deep sooth pristine oasis. I had no idea that part of the river existed. The other part always look shallow, fast and rocky.
