The term "sulcus" (plural: sulci) describes terrain with long, parallel fractures. Sulci are very common on icy moons -- for example, at the south pole of Enceladus, as seen in PIA11686.

It may point to an episode of tectonic deformation resulting from the evolution of the crater, which is the second largest on Ceres. The impact that formed Yalode heated Ceres'…
