Excursion

STURT GORGE PART 2: EVIDENCE FOR THE START OF THE STURTIAN GLACIATION WHEN THE WORLD BECAME ICED UP

Sunday March 29th

Sturt Gorge is flanked by rocks deposited during a worldwide glacial episode that occurred around 700 million years (Ma) ago. First recognised here in 1901 by Professor Walter Howchin, the glacial episode is known geologically as the Sturtian glaciation and the rock formation itself, the Sturt Tillite, is world famous. The aim of this excursion is to observe the start of the glaciation.

"I Love Lusi: History of a Mud Volcano"
Thursday 2nd April 2026 at 7:00 pm

Born 29 May 2006 and not dead yet, Lusi is the biggest mud volcano in the world. It has swallowed up 13 villages and caused the displacement of 50,000 people. Farmland has been laid waste and houses submerged to the rooftops. A perimeter levee of 4 m height surrounds an area of 8.2 km2 - that alone contains 206 million barrels of mud. But that’s not all. Mud initially flowed way beyond the containment levee, there has been subsidence of 7 to 25 m, and mud has periodically been released down the Porong River.
