Hutt Lagoon is a salt lake near the coast north of the mouth of the Hutt Riv­er in West­ern Aus­tralia. The lake’s water is pink due to the pres­ence of two types of algae that pro­duce a red­dish-orange organ­ic pig­ment called beta-carotene. It is used as a col­or­ing pig­ment in food and med­i­cine. Hutt Lagoon is the world’s largest sea­weed farm sys­tem pro­duc­ing this pig­ment.

14 km long and 2 km wide, the lagoon is sep­a­rat­ed from the Indi­an Ocean by a beach ridge and a sys­tem of dune bar­ri­ers. Hutt is fed by sea­wa­ter seep­ing over the bar­ri­er crest, but high lev­els of evap­o­ra­tion bal­ance the influx of salt result­ing in high salin­i­ty lev­els that are con­stant through­out the year. Dur­ing the sum­mer, approx­i­mate­ly 95% of the sur­face is dry flat salt.

Cur­rent­ly, approx­i­mate­ly 450 hectares of the approx­i­mate­ly 2,500 hectares of Hutt Lagoon are used to grow sea­weed from which Beta-carotene is extract­ed. Beta-carotene is used as a nat­ur­al col­or in food and is also a rich source of Vit­a­min A. Nat­u­ral­ly, beta-carotene can also be found in var­i­ous fruits, veg­eta­bles and grains.

These shots were tak­en by British pho­tog­ra­ph­er Steve Back while fly­ing over the lake. An archi­tec­tur­al pho­tog­ra­ph­er, Back was work­ing in the field when he became inter­est­ed in pho­tograph­ing sea­weed. He rent­ed a small plane and head­ed south­west close to the coast. While fly­ing over the lagoon, he was struck by the beau­ty and sym­me­try of the farm south of Kalbar­ri.

“Below, the pink col­oration isn’t too obvi­ous and a bit unim­pres­sive, but from the air it looks fan­tas­tic,” says the pho­tog­ra­ph­er.
