That's still pretty shallow, what ground types/changes do you remember mate?Long story short, about 40 years ago a mate and I went to Inglewood ( the potato diggings) and we noted that the ground between two not so deep shafts hadn’t been touched except for a deposit of gravel which had been tossed from the other shafts. So we dug down about 8’ x 4’ and found , yep, absolutely nothing. However, Scotty, with your experience, if it looks good you should process it. Cheers Mackka
