This portion of the Lewis River trail has three main waterfalls. There's a fourth pretty big one, but the viewpoint leaves something to be desired. Probably the most famous of them is Lower Lewis River Falls - with good reason. It's a beauty. It's also right next to a campground, so I imagine that during summer it's quite a busy area. There are signs informing people that someone died there so be careful in the river upstream. Actually I would be surprised if only one person died there. The crazy thing is that there is a wooden staircase and the stairs cut into the rock right above the waterfall. Slip there and you would be right in the main channel headed over the brink.
In my experience, Middle and Upper Lewis River Falls don't photograph all that well. Or the photos certainly aren't representative of actually being there. All three of the main falls have one main channel powerfully funneling the lion's share of the river. The rest of the water flows along shallowly sloped rock and flows over the much wider ledges. I suppose that it's ironic for me to speak of photographs not being representative of the scenes since I appear to be a big fan of long exposures. But then I suppose one could delve into the discussion of dynamic range limits or other such issues which make photographs not look like seeing a scene in person.
One of the things I liked about this particular spot is the bedrock in the foreground. It sort of reminds me of argillite. I would be interested to find out if anyone knows what it actually is.
