Sinkhole

Sinkholes were large cavities that formed on the surface of several planets including Malastare and Utapau. During the Clone Wars, the detonation of an electro-proton bomb at the Battle of Malastare created a giant sinkhole which unearthed an ancient monster called the Zillo Beast. Several cities including Pau City on the planet Utapau were build around sinkholes.
