Hi all, went out for a drive around Daylesford, Newstead Castlemaine area and noticed formations of rock running up and over hills etc. they were all running in straight lines in various locations, some places 7-8 lines wide, not sure what type of rock they were, if you've driven from Daylesford to guilford you can see them on a property running over a hill next to the road, anyone got any ideas or info?
