Saturn’s B ring has shadows cast by “mountainous waves of icy rubble extending more than 2 miles high above the 30-feet-thick disk of debris that forms the plane of the rings” :

I have often thought: What a surreal sight this would be if you were flying low across the rings in a shuttle craft. To your eyes, the rings would seem like a gleaming white, scored, gravelly
sheet below you, extending nearly to infinity. And as you flew, you would see in the distance a wall of rubble that, eventually, as it neared, you would come to realize towered 2 miles above your head. There isn’t another sight like it in the solar system!
Michael Carroll, a beloved and skilled astronomical artist, took this idea, mentioned often in my public lectures, and turned it into a piece of art.
