[2] Shangri-La is studded with bright 'islands' of higher ground, called inselbergs, which are thought to be protrusions of the icy bedrock.
[2] The composition of the sand itself is unknown and a current area of research, although orbital observations strongly suggest organic compounds.
It has been speculated that the sand may have eroded from sources that no longer exist, although other hypotheses, such as transport of evaporites from hydrocarbon seas and precipitation of organics from the atmosphere have been proposed.
[3] The Huygens probe landed on the west part of Shangri-La, close to the boundary with Adiri.
The planned lander rotorcraft Dragonfly will land on Shangri-La, and will fly toward the Selk impact crater.
