May FOBIF walk on Mt Alexander

web-quarry.Mt-Alex-0823Starting and finishing at the Oak Forest, Doug Ralph led the group of about 20 around the western flanks of Mt Alexander, taking in 2 or 3 disused granite quarries. Doug related some interesting stories from the history of these quarries, and Prof. Julian Hollis gave us a brief synopsis of his current geological research into a mineralogical relationship between the granite of Mt Alexander and volcanic rocks which have been drawn from deep in the crust and ejected at Mt Franklin.

It was a balmy autumn day, and though a relatively tough walk (some of it was off track) it was enjoyed by all who participated.


In the Oak Forest there were many examples of Fly Agaric fungi, (Amanita muscaria) like this one complete with footstool.


At the lunch stop, a large slab of granite was completely covered with Moss and Lichen. Such bio-crusts considerably accelerate the weathering and breakdown of rocks
