This Friday 29th July at 8pm for our members night we have our own Jacquie Milner speaking to us about "A visit to four impact structures in WA":
The ancient and heavily eroded landscape of Western Australia offers an opportunity to see some of the major features of meteorite impact sites. In September 2004 a small group of members from the Perth Observatory Volunteer Group and the Geological Society of WA toured around four impact structures in central Western Australia: The Yarrabubba Impact Structure, revealing the deep effects of a strike; the renamed Shoemaker Impact Structure (formerly known as the Teague Ring) displaying some of the surface features of a complex crater; the well-known Dalgaranga Crater, a good example of the simple crater; and the Yallallie Impact Structure, formed in an unusual setting. Together these structures provide an overview of impact structure geology, both above and below ground.
If you have a telescope and would like to know how to use it, or alternatively, would like to show it off to us, please bring it along!
