Big surface clumps of dirt ( modern compacted top soil )is a nuisance to deal with and slows the screening work.
I found a good way to deal with the problem
Just take the block over to a neighboring table
What can they say ??
So it's goodby problem
This is great
Later in the day they moved the tables around, Our new neighbors to get the dirt clumps was that louisiana crew
There is a slight snag in my new system that I'll have to work out..
Later in the Day Louisiana Jamie came over to MY side of the table with a 100 pound boulder then a half a tree trunk
Hal, I just thought you were being generous and sharing your dirt. I'd hate to tell you how many bird points we found in those clods, don't want you to feel bad.
Bird points,,,sh**** points
I check every clump before relocating it...if it doesn't have an inch or two of something worked sticking out of it...I'm not interested
