<<Moving bulldozers tend to be surrounded by large piles of moving dirt.>> Those are called spoil banks. The first few passes have dirt falling off both sides of the blade that build berms that keep the dirt in front of the blade on the next passes. Those berms tend to not be really stable as the clods haven't settled. BTW, I remember back in the 60s a group of civil rights activists laid down in front of a dozer to stop it. It stopped but when the operator backed up to go around them he didn't see the 4 protesters that had laid down behind him to keep him from backing up.
