local digger, once you go past the top point of the inverted "V" that is where you get no more gold or colours, the same as when you go outside the edges of the inverted "V" you get no more gold or colours.It should be a matter of coming back down to the tip of the inverted "V" where you begin to get colours again and go down deeper right there, sample and wash the dirt as you go down, thats what the old timers did anyway GE
