What are those black things? Rocks? Do they naturally arrange in those lines?
Hi Nathan, those are “moqui marbles.” I don’t know much about them except that they’re iron-based concretions that are found in the Navajo sandstone. They weather out and then collect on the rocks. I’ve never seen remotely so many as in these pics.
Regarding the patterns, I think it’s just wind and water arranging them in low spots on the slickrock. Or it’s aliens.
Great Photos! I’ve gotta make it down there sometime!
Definitely aliens. I really like the moqui marble shots.
Great photos! One picture in the middle looks like the view at the Wave.
