[QUOTE="Metabet, post: 672396, member: 25206"] Standing atop a gully in a heavily investigated (for gold) Victorian bush landscape, behind is a dam dug in the late 1800s/early 1900s for surfacing the gully. I understand the old-timers used high pressure water jets to remove the top soil to reveal any surface gold.
