[QUOTE="Telling Ghosts, post: 481136, member: 14730"] Thanks for the great info Sushi, it's answered a lot of questions and raised many more! So basically if I'm understanding correctly, all the stuff that I found has ended up there from the same thing, a flood event at some point in time, some of it has traveled further than the rest to get there and there's thousands of years worth of stuff going on in each shovel I'm taking out? When you say the quartz hasn't traveled far due to how little erosion it has experienced, is there any way of quantifying that? Are we talking, it washed down from the gully and sat there, traveled hundreds of meters down river, or are there too many variables to know? Very cool to have found some sapphire, I've looked a geological map of the area and there is isolated areas of basalt not far from where I was digging, does it stand to reason that if I was to look closer to these I could increase the likelihood of finding more sapphires? I put the light up to that last rock and it's opaque :( I think I burnt out my retinas double checking though. [/QUOTE]
