Because I am a great fan of Time Team on Foxtel, I am constantly puzzled by the amount of digging and removal of soil that is required to reveal ""recent "" History. I know there is a rapid build up of dust in my home on a daily basis. I often tell people that this dust in my home is from the Sahara Desert, having been drawn upwards in weather events over this desert, and then entering the Jet Stream in the Stratosphere to fall back to earth in my Latitude. When we have vast Dust Storms in Australia it is not uncommon for the Alps in the South Island of New Zealand to receive a coating. So Australia goes to New Zealand. We are all Anzacs, new Zealanders come to Australia to escape the dust. But say, when Time Team go looking for Iron Age or Stone Age, they expect to remove built up soil, sometimes averaging three to six feet of soil. Surely our surface soils to not break down or accumulate at the rate that appears to be happening in England etc? If this was the case our houses would visually be seen to sinking below foundation level. Wind moves sand at a rapid rate under certain conditions, hence our northern railways often required clearance in the 20th Century before Trains could continue. But surely these conditions do not occur in England and Scotland? How come the, to me anyway, rapid soil deposits on what is now farmland ( in most cases ) in these Countries? Would appreciate some enlightening on this Subject. westwind.![]()
