As we drove south from Kalbarri on our way to Cervantes, we were amazed to see this Pink Lake at Port Gregory. It was quite an amazing bright pink colour, and the lagoon went on for kilometres. The Hutt Lagoon is a superb example of a naturally occurring phenomenon that occurs when algae ‘blooms’ and produces beta carotene – a pigment that has become a lucrative aquaculture crop.
We stayed in Cervantes which is a small cray-fishing village on the Western Australian coast. Nambung National Park is around 20 km from Cervantes. The hundreds of limestone formations that make up The Pinnacles in the National Park are quite amazing to see. Each separate pinnacle can be up to five metres high, although most are smaller than that.
Some of the pinnacles are quite sculptural in appearance, and look wonderful set amongst the rippling yellow sands of the park.
We spotted these galahs perched on top of a pinnacle. There are meant to be lots of animals that live in the park, but most are nocturnal except for kangaroos and emus. However these galahs were the only living things we saw.
As the evening came upon us, an approaching storm made an interesting backdrop to the spectacle of the pinnacles spread across the horizon.
On leaving the park, this white expanse in the distance caught our eye. The sands are so white it doesn’t take much imagination to see it as a snow covered hill.
Returning to Cervantes, where we were staying, we called into Lake Thetis which is world renowned for the stromatolites that grow there. Lake Thetis is a shallow lake formed between sand dunes, about one-and-a-half kilometres inland, dating back around three or four thousand years. It is very salty, and is fed by rainfall and groundwater, so its water level rises and falls with the seasons. Although salty, it is full of life, the most obvious being the cyanobacteria which have produced the stromatolites along the south and western sides, and the microbial mats which line the lake all round. Until the 20th century, the only evidence of stromatolites was in fossil form and scientists presumed that these unique biofilms were extinct.
