An full Easter moon rises as the sun sets over one of the most significant archaeological sites in the world. The Walls of China is a lunette that sits on the eastern side of the ancient Lake Mungo stretching for more than 33 km. It is made up of three distinct layers; the reddish Gol Gol layer, formed between 100,000 and 120,000 years ago,while the archaeologically prolific middle greyish layer or Mungo layer, deposited between 50,000 and 25,000 years ago with the most recent Zanci layer, which is pale brown, being laid down mostly between 25,000 and 15,000 years ago. The scientific evidence shows that Aboriginal people have lived at Mungo for at least 45,000 years. This is the dated age of the oldest stone artifacts and human remains that have been found so far, and represents a lineage that extends back over some 2000 generations. Lake Mungo dried up almost 14,000 years ago and is located in the deep Outback of NSW, Australia
First light of the day tries to break through the clouds over Mt Ida and the Travellers Range. The prominent cliffs and columns of the central highlands are made of Jurassic dolerite. This shot was taken from the southern end of Lake St Clair which is Australia's deepest lake owing its depth of 160m (or 525 ft) to its glacial origin. Unlike mainland Australia it is believed that Tasmania experienced four phases of major glaciation with a single ice cap covering about 4,000 sq km of the northwestern part of the central plateau along with other smaller isolated ice caps and valley glaciers. During these glacial periods sea levels were low enough to open the Bassian landbridge connecting Tasmania to Australia with grasslands and scrub heath found across the area where the Bass Strait now lies.

Foreboding clouds roll across Medicine Lake while it sits in winter hibernation. While the Maligne River pours into the lake from the south, the lake is actually a geological anomaly as there is no visible exit to the lake. The water however drains out through a cave system formed in the slightly soluble limestone rock. It does not surface again for 16km where Maligne Canyon improbably cuts its way out of the ground. The sinking river system is thought to be one of the largest inaccessible cave systems anywhere in the world. Jasper National Park, Alberta, Canada
