Lake Gairdner in central South Australia is pictured in this image acquired by Japan’s ALOS satellite on 1 December 2009.
The Lake Gairdner National Park – which includes the nearby lakes Everard and Harris – was established in 1991 for its signiﬁcant wildlife habitat and natural features.
While the area is hot and dry in summer, spring brings water and is a popular destination for birdwatchers. Red and western grey kangaroos, emus and feral camels can also be seen here.
When flooded, Gairdner is one of the largest salt lakes in Australia, more than 160 km long and 48 km wide. But when dry, the vast salt pan attracts racers attempting to set land speed records and is the site for the annual Speed Week event.
This image shows mostly the dry, salt-crusted lakebed, while the islands appear brick-red.
