Nice ones! So what do they do with the top soil anyway? Be cool if you could sift it before they haul it off. Get a giant sifter.[/QUOTE
Lots of times they make long strips mounds along the edge or just pile other dirt over it. Sometimes they haul it away but it just becomes very difficult to find anything. I had been watching this one small lot for 5 years waiting for it to be cleared. I found a lot when they cleared the one beside it. I stopped by the day they cleared and found the quartz point. Couldn't see anything much because they had pushed the mud around over top. It rained hard that night and I now there were some more washed up so I stopped by mid morning and they had already dug a hole in the back of the lot and pushed off the top layer and covered it with dry dirt.
