The fog was the entire reason we went. The entire trip had a nearly surreal feeling to it. We started hiking about 30 minutes before first light, and with other kinds of trees already having shedded their leaves, the trail was spotted with bright yellow that almost seemed to glow. (it almost felt like I was in the movie Avatar lol). The tops of the canyon were blanketed in fog 700 feet above us, but it was clear at ground level. Once the sun rose above the horizon, the fog began to pour down the canyon. It was almost unearthly the way we were able to watch wave after wave pour in over us. We endured a few showers, and resorted to throwing our coats over our cameras which were already mounted on the tripods and set up, while we huddled under the nearest tree. After capturing a moment that I will never forget, we packed up and started the hike back to the truck. On our way down, it started to rain harder than before. We heard the sound of rushing water, and looked at the vertical cliffs of the canyon walls around us. They had absolutely come to life in the rain, with dozens of waterfalls all around, some of them falling uninterrupted the entire 700-800 feet to the canyon floor. Ten minutes later when the rain stopped, the waterfalls disappeared.
It was truly an amazing experience that I will never forget. I hope we can at least partially experience the same thing next weekend. The weather is supposed to be pretty wet for at least another 5 or so days, so even if the storm is passed we will get fog once the sun hits the cliffs.
