Clear skies above Western Australia reveal deep red and orange deserts, bright white salt pans, deep brown mountains, and bright green pasturelands. Perth, the largest city in southwestern Australia, sits on the western coast near the northern end of the Darling Range of mountains and is visible as a roughly triangular spot of grey on the land. Far to the north of Perth, two-pronged Shark Bay points to the northwest. Shark Bay is a World Heritage Site famous for being home to over 10,000 species of seagrass, manatees (called dugongs in Australia), and the oldest-known form of life: stromatolitic microbialities.
