Not much rocket science there. look at the vertical depths and plot those against the elevations and it shows a bit of a dip but definately a halo. The pattern conforms to what we have experience with and while it's widely distributed it's showing high concentrations around the perimiter as expected. We need a chappy map showing the elevations so you can see what I mean. I suspect the very northern end will be broken up.

I would have hoped 430 would has been a little more East but it should show us more of the same pattern. They probably have ground chemistry to back it up too. 520 probably dips to the south. Too bad we lost that one. I suspect it will show more of the SC pattern and suggests a continuation.

I think that just north between 426 and 430 is a hot spot. A combination of the maps suggests this. We could possibly find the reminants of a vent there. That would get very exciting. Sure would be nice if they gave us a composite map with all the line numbers.
