Had a couple days out camping with the kids out past Daylesford in Vic. The creek that normally runs through our little valley was dry so the kids spent a fair bit of time exploring it picking up bits of quartz which had some interesting crystals? in them. None were real big but some were crystal (excuse the pun ) clear while others were clear but with a yellow hue to them. Nothing real spectacular I don't think but fun none the less. Cant wait to get my macro lens to get some better close ups. One pic below.
