Different colours on the map represent the different kinds of rocks that you encounter as you travel Phillip Island. The map includes a legend that shows which rocks are represented by each colour. (There is an outcrop of Cambrian greenstone at Kitty Miller Bay that is not shown on the map because the outcrop is too small to represent.) This map will help you recognise what rocks you are looking at as you explore the island. With time you will become familiar with them. The legend is arranged like a time line, with the oldest rocks at the bottom, and the youngest rocks at the top. The order is not arbitrary, but worked out by observing the relationships between the rocks in the field. You will be able to see some of these relationships at some of the sites inspected.
Nineteen geological sites are described in the guide, and these are shown on the map. Site #1 is to the south west at the Nobbies. The other sites follow a general anticlockwise path. For each site, the guide describes how to access the site, and whether the access is difficult or easy. For each site too, the various features of the rocks are explained, highlighting what to look out for and notice.
On the Creation Supercamp we encouraged folk to visit the sites with friends. We suggested that someone read the commentary from the guide aloud for all to hear, as if there was a human guide speaking. We encouraged folk to discuss and observe the features together in order to ensure they can see and understand what is described. We also encouraged folk to answer the questions in the guide, and to make notes and sketches.
Geology is about history, and history is about understanding our past. Our view of our past impacts our actions in the present, and our vision for the future. Remarkably, our understanding of geology impacts us at the deepest personal level, your image of who you are, your outlook, and your purpose and goals. That is why we prepared the self-guided Phillip Island excursion.
