Nearly all of us have driven in the Adelaide Hills between Montacute Road and the freeway, and lots of us have looked at the 1:50,000 Adelaide geology sheet, but how many of us have put the two together and would know where they are, geologically speaking? On this field trip, as we wend our way through the hills, we’ll make a few stops to marvel at the repeating fault block pattern, their shear zone boundaries, and the formations and their contacts. We’ll learn how the geology has shaped the geomorphology, understand why the hillscarring quarries are where they are, and why Mt Lofty is so lofty.

At this stage of the planning, there are about 45 km of travelling and about 7 stops. There will also be a running commentary from David to all vehicles using the facility on our mobile phones to have multiple handsets on the same call. A short walk of less than 1 kilometre on steepish track is required at Morialta and another of about 2 kilometres in Chambers Gully. Bulletin of the Field Geology Club of South Australia (Inc) Vol. 50 No. 3 Page 5.

Bring your own lunch to have on Mt Lofty. Expected to start at 9 am at Morialta and return there at 3 pm.

Depending on numbers, we may rent small buses as there may be too many vehicles to park repeatedly along hills roads, in which case there will be a fee to attend.

Detailed instructions and excursion notes will be sent to those who sign up. You can sign up at the meeting on April 1st, or contact Bob Major at bobmajor1940@gmail.com or mobile 0149 800 242.

Please sign up by 8 April so we know if buses will be required. 

Remember, when you are looking up-dip, you are looking down-section, and vice versa.
