Thrombolites, Pelicans and Orchids: Trip to Lakes Richmond and Clifton, south of Perth in Western Australia. Doug and Ellen saw the living and fossilized Thrombolites, descendents of the oldest lifeforms on earth, dating back over 3.5 billion years and responsible for adding oxygen to the Earth's atmosphere, making it inhabitable for animals, including humans. They also saw Australian Pelican, Egrets, and Cowslip, Pink Fairy and Enamel Orchids as they walked the Lake Clifton trail in Yalgorup National Park. September 2011.
