Other geological features Enhanced-color view of part of Conamara Chaos , showing ice rafts up to 10 km (6 mi) across. White areas are ejecta from the crater Pwyll . Craggy, 250 m high peaks and smooth plates are jumbled together in a close-up of Conamara Chaos . Other features present on Europa are circular and elliptical lenticulae ( Latin for "freckles"). Many are domes, some are pits and some are smooth, dark spots. Others have a jumbled or rough texture. The dome tops look like pieces of the older plains around them, suggesting that the domes formed when the plains were pushed up from below. [40] One hypothesis states that these lenticulae were formed by diapirs of warm ice rising up through the colder ice of the outer crust, much like magma chambers in the Earth's crust. [40] The smooth, dark spots could be formed by meltwater released when the warm ice breaks through the surface. The rough, jumbled lenticulae (called regions of "chaos"; for example,
