A geology nerd interlude

I was surprised to find the soil near a high point of the Powerline trail was... not red! It also had a lot of clay in it, which is peculiar in a place that's so geologically young -- although Kaua'i is much older than the other Hawaiian islands.
Further down the trail, the soil was more the expected color, with some veins of even more iron-rich material.

I know absolutely zip about geology and why the clay is surprising, but there is a huge mud flat by Kuli'ou'ou that is basically all clay.
