Details

 

The Port Elliott and Middleton area is an excellent location to observe the relationship between granite intrusions into the surrounding Cambrian host rock. Also, superimposed over these rocks are effects of the Permian glaciation.There are four locations we will visit on this excursion. The first two will deal with the Encounter Bay Granites at Pt Elliot (The Intruder) and the second two looking at the Middleton Sandstone (The Host).
Three sites have short walks and one site a more extended walk. Although most of the walks will be on pathways, there will be some scrambling over uneven rocks and boulders, so a good pair of walking boots and maybe walking sticks will be needed.
The sign-up sheet will be available at the April meeting.
