I'm gonna turn up the geological nerdiness to a macro scale for a minute...
This is a syncline:
Not far off, to what would be the left in this photo, is a thrust fault subduction zone where the younger plate was overtaken by an older plate. (It's a cool spot to explore. There's a 2 ft wide creek at the center of it. Within a couple of steps, you can be in 2 very different geologic, and in turn ecologic, environments.) The massive thrust pressure and relatively high rate of speed at which the thrusting events occurrd created a series of dramatic synclines and anticlines that make up the backbone of the entire ridge. This particular section buckled and collapsed, creating the canyon that channels the river that is there today.

Of course I was excited, so I doubled down on searching for others in that area. I went up and down that stretch of river, as the old man swam a few hundred yards away. I found nothing but a few underwhelming fossils.
On my way back to the spot where you can easily ascend the bank, the old man came walking out of the water and up to me. He said "Here, I found this for you. It's not an agate but it's pretty," and he handed me a sun bleached mussel shell with a perfectly shimmery interior.
I said, "Oh that's beautiful, thank you," but by the time I looked up, he was over the bank and gone. I went up the bank, too, and he was nowhere to be seen. No car. No one walking on the road. Nothing. I'm not sure if I talked to God or a magical merman today, but I found 1 pretty little agate and received an awesome gift, so either way, I'm happy about it. ๐
