Iapetus' Equatorial Ridge
IAPETUS · the walnut seam
A mountain range up to 13 kilometers tall that runs almost perfectly along Iapetus' equator, giving the moon the look of a walnut. Nothing else like it exists, and its origin is genuinely unsolved: a fossil bulge from a fast spinning youth, or the wreckage of an ancient ring that rained down onto the equator. A mystery you can see from across the room.
